  SGM4056 high input voltage charger general description the SGM4056 is a cost-effective, fully integrated high input voltage single-cell li-ion battery charger. the charger uses a cc/cv charge profile required by li-ion battery. the charger accepts an input voltage up to 26.5v but is disabled when the input voltage exceeds the ovp threshold, typically 6.8v (SGM4056-6.8) or 10.5v (SGM4056-10.5), to prevent excessive power dissipation. the 26.5v rating eliminates the over- voltage protection circuit required in a low input voltage charger. the charge current and the end-of-charge (eoc) current are programmable with external resistors. when the battery voltage is lower than typically 2.55v, the charger preconditions the battery with typically 18% of the programmed charge current. when the charge current reduces to the programmable eoc current level during the cv charge phase, an eoc indication is provided by the chg pin, which is an open-drain output. an internal thermal foldback function protects the charger from any thermal failure. two indication pins ( ppr and chg ) allow simple interface to a microprocessor or leds. when no adapter is attached or when disabled, the charger draws less than 1 a leakage current from the battery. the SGM4056 is available in green tdfn-33-8l, tdfn-23-8l, tdfn-22-8l and soic-8 (exposed pad) packages and is rated over the -40 to +85 temperature range. features ? complete charger for single-cell li-ion or polymer batteries ? integrated pass element and current sensor ? no external blocking diode required ? low component count and cost ? programmable charge current ? programmable end-of-charge current ? charge current thermal foldback for thermal protection ? 2.55v trickle charge threshold ? 6.8v input over-voltage protection for SGM4056-6.8 ? 10.5v input over-voltage protection for SGM4056-10.5 ? 26.5v maximum voltage for the power input ? power presence and charge indications ? less than 1 a leakage current off the battery when no input power attached or charger disabled ? available in green tdfn-33-8l, tdfn-23-8l, tdfn-22-8l and soic-8 (exposed pad) packages applications mobile phones blue-tooth devices pdas mp3 players stand-alone chargers other handheld devices rev. a. 1 sg micro corp www.sg-micro.com

high input voltage charger 11 SGM4056 sg micro corp www.sg-micro.com charge current charge voltage trickle cc cv 4.2v i ref time 2.55v chg 74% i ref i min chg indication 18% i ref figure 3. typical charge profile operation the SGM4056 charges a li-ion battery using a cc/cv profile. the constant current i ref is set with the external resistor r iref (see figure 1) and the constant voltage is fixed at 4.2v. if the battery voltage is below a typical 2.55v trickle charge threshold, the SGM4056 charges the battery with a trickle current of 18% of i ref until the battery voltage rises above the trickle charge threshold. fast charge cc mode is maintained at the rate determined by programming i ref until the cell voltage rises to 4.2v. when the battery voltage reaches 4.2v, the charger enters a cv mode and regulates the battery voltage at 4.2v to fully charge the battery without the risk of over charge. upon reaching an end-of-charge (eoc) current, the charger indicates the charge completion with the chg pin, but the charger continues to output the 4.2v voltage. figure 3 shows the typical charge waveforms after the power is on. the eoc current level i min is programmable with the external resistor r imin (see figure 1). the chg pin turns to low when the trickle charge starts and rises to high impedance at the eoc. after the eoc is reached, the charge current has to rise to typically 74% i ref for the chg pin to turn on again, as shown in figure 3. the current surge after eoc can be caused by a load connected to the battery. a thermal foldback function reduces the charge current anytime when the die temperature reaches typically 115 . this function guarantees safe operation when the printed circuit board (pcb) is not capable of dissipating the heat generated by the linear charger. the SGM4056 accepts an input voltage up to 26.5v but disables charging when the input voltage exceeds the ovp threshold, typically 6.8v for SGM4056-6.8 and 10.5v for SGM4056-10.5, to protect against unqualified or faulty ac adapters. ppr indication the ppr pin is an open-drain output to indicate the presence of the ac adapter. whenever the input voltage is higher than the por threshold, the ppr pin turns on the internal open-drain mosfet to indicate a logic low signal, independent on the en pin input. when the internal open-drain fet is turned off, the ppr pin leaks less than 20a current. when turned on, the ppr pin is able to sink at least 15ma current under all operating conditions. the ppr pin can be used to drive an led (see figure 1) or to interface with a micro- processor.
high input voltage charger 12 SGM4056 sg micro corp www.sg-micro.com operation power good range the power good range is defined by the following three conditions: 1. v in > v por 2. v in - v bat > v os 3. v in < v ovp where the v os is the offset voltage for the input and output voltage comparator, discussed shortly, and the v ovp is the over-voltage protection threshold given in the electrical characteristics table. all v por , v os , and v ovp have hysteresis, as given in the electrical characteristics table. the charger will not charge the battery if the input voltage is not in the power good range. input and output comparator the charger will not be enabled unless the input voltage is higher than the battery voltage by an offset voltage v os . the purpose of this comparator is to ensure that the charger is turned off when the input power is removed from the charger. without this comparator, it is possible that the charger will fail to power down when the input is removed and the current can leak through the pfet pass element to continue biasing the por and the pre-regulator blocks. dropout voltage the constant current may not be maintained due to the r ds (on) limit at a low input voltage. the worst case r ds (on) is at the maximum allowable operating temperature. chg indication the chg is an open-drain output capable of sinking at least 15ma current when the charger starts to charge, and turns off when the eoc current is reached. the chg signal is interfaced either with a microprocessor gpio or an led for indication. en input en is an active-low logic input to enable the charger. drive the en pin to low or leave it floating to enable the charger. this pin has a 200k ? internal pull-down resistor so when left floating, the input is equivalent to logic low. drive this pin to high to disable the charger. the threshold for high is given in the electrical characteristics table. iref pin the iref pin has the two functions as described in the pin description section. when setting the fast charge current, the charge current is guaranteed to have 12% accuracy with the charge current set at 500ma. when monitoring the charge current, the accuracy of the iref pin voltage vs. the actual charge current has the same accuracy as the gain from the iref pin current to the actual charge current. operation without the battery the SGM4056 relies on a battery for stability and works under ldo mode if the battery is not connected. with a battery, the charger will be stable with an output ceramic decoupling capacitor in the range of 1f to 200f. in ldo mode, its stability depends on load current, c out , etc. the maximum load current is limited by the dropout voltage, the programmed i ref and the thermal foldback. thermal foldback the thermal foldback function starts to reduce the charge current when the internal temperature reaches a typical value of 115 .
high input voltage charger 13 SGM4056 sg micro corp www.sg-micro.com application information input capacitor selection the input capacitor is required to suppress the power supply transient response during transitions. mainly this capacitor is selected to avoid oscillation during the start up when the input supply is passing the por threshold and the vin-bat comparator offset voltage. when the battery voltage is above the por threshold, the v in - v bat offset voltage dominates the hysteresis value. typically, a 1f x5r ceramic capacitor should be sufficient to suppress the power supply noise. output capacitor selection the criterion for selecting the output capacitor is to maintain the stability of the charger as well as to bypass any transient load current. the minimum capacitance is a 1f x5r ceramic capacitor. the actual capacitance connected to the output is dependent on the actual application requirement. layout guidance the SGM4056 uses thermally-enhanced tdfn and soic packages that have an exposed thermal pad at the bottom side of the packages. the layout should connect as much as possible to copper on the exposed pad. typically the component layer is more effective in dissipating heat. the thermal impedance can be further reduced by using other layers of copper connecting to the exposed pad through a thermal via array. each thermal via is recommended to have 0.3mm diameter and 1mm distance from other thermal vias. input power sources the input power source is typically a well-regulated wall cube with 1-meter length wire or a usb port. the SGM4056 can withstand up to 26.5v on the input without damaging the ic. if the input voltage is higher than typically 6.8v (SGM4056-6.8) or 10.5v (SGM4056-10.5), the charger stops charging.
