Lithium Battery Protection Circuit for One Cell Battery Packs
The MC33349 is a monolithic lithium battery protection circuit that is designed to enhance the useful operating life of a one cell rechargeable battery pack. Cell protection features consist of internally trimmed charge and discharge voltage limits, discharge current limit detection, and a low current standby mode when the cell is discharged. This protection circuit requires a minimum number of external components and is targeted for inclusion within the battery pack. * Internally Trimmed Charge and Discharge Voltage Limits

OPERATING DESCRIPTION
VD1 / Over-Charge Detector VD1 monitors the voltage at the VCELL pin (VDD). When it exceeds the over-charge detector threshold, VDET1. VD1 senses an over-charging condition, the CO pin goes to a "Low" level, and the external charge control, Nch-MOSFET turns off. Resetting VD1 allows resumption of the charging process. VD1 resets under two conditions, thus, making the CO pin level "High." The first case occurs when the cell voltage drops below "VDET1 - VHYS1." (VHYS1 is typically 200 mV). In the second case, disconnecting the charger from the battery pack can reset VD1 after VDD drops between "VDET1" and "VDET1 - VHYS1". After detecting over-charge, connecting a load to the battery pack allows load current to flow through the parasitic diode of the external charge control FET. The CO level goes "High" when the cell voltage drops below VDET1 due to load current draw through the parasitic diode. An external capacitor connected between the Gnd pin and Ct pin sets the output delay time for over-charge detection. The external capacitor sets up a delay time from the moment of over-charge detection to the time CO outputs a signal, which enables the charge control FET to turn off. If the voltage fault occurs within the time delay window. CO will not turn off the charge control FET. The output delay time can be calculated as follows: t [sec] VDET1 parasitic diode of the external discharge control FET. The DO level goes "High" when the cell voltage rises above VDET2 due to the charging current through the parasitic diode. Connecting a charger to the battery pack will instantly set DO "High" if this causes VDD to rise above VDET2. When cell voltage equals zero, one can charge the battery pack if the voltage is greater than the minimum charge voltage, VST. Output delay time for the over-discharge detection (tVDET2) is fixed internally. If the voltage fault occurs within the time delay window, DO will not turn off the discharge control FET. A CMOS buffer sets the output of the DO pin to a "High" level of VDD and a "Low" level of Gnd. VD3 / Excess Current Detector, Short Circuit Detector Both the excess current detector and the short circuit detector can work when the two control FET's are on. When the voltage at the P- pin rises to a value between the short circuit protection voltage, VSHORT, and the excess current threshold, VDET3, the excess current detector operates. Increasing V(P-) higher than VSHORT enables the short circuit detector. The DO pin then goes to a "Low" level, and the external discharge control Nch MOSFET turns off. Output delay time for excess current detection (tVDET3) is fixed internally. If the excess current fault occurs within the time delay window, DO will not turn off the discharge control FET. However, when the short circuit protector is enabled, DO can turn off the discharge control FET. Its delay time would be approximately 5 s. The P- pin has a built-in pull down resistor, typically 100 kW, which connects to the Gnd pin. Once an excess current or short circuit fault is removed, the internal resistor pulls V(P-) to the Gnd pin potential. Therefore, the voltage from P- to Gnd drops below the current detection thresholds and DO turns the external MOSFET back on. -NOTE- If VDD voltage is higher than the over-discharge voltage threshold, VDET2, when excess current is detected the IC will not enter a standby mode. However, if VDD is below VDET2 when excess current is detected, the IC will enter a standby mode. This will not occur when the short circuit detector activates.

A level shifter incorporated in a buffer driver for the CO pin drives the "Low" level of CO pin to the P- pin voltage. A CMOS buffer sets the "High" level of CO pin to VDD. VD2 / Over-Discharge Detector VD2 monitors the voltage at the VCELL pin (VDD). When it drops below the over-discharge detector threshold, VDET2, VD2 senses an over-discharge condition, the DO pin goes to a "Low" level, and the external discharge control Nch MOSFET turns off. The IC enters a low current standby mode after detection of an over-discharged voltage by VD2. Supply current then reduces to approximately 0.3 A. During standby mode, only the charger detector operates. VD2 can only reset after connecting the pack to a charger. While VDD remains under the over-discharge detector threshold, VDET2, discharge current can flow through the MOTOROLA ANALOG IC DEVICE DATA

Figure 23. Typical Application Circuit
Technical Notes R1 and C1 will stabilize a supply voltage to the MC33349. A recommended R1 value is less than 1 kW. A larger value of R1 leads to higher detection voltage because of shoot through current into the IC. R2 and C2 stabilize P- pin voltage. Larger R2 values could possibly disable reset from over-discharge by connecting a charger. Recommended values are less than 1 kW. After an over-charge detection even connecting a battery pack to a system could probably not allow a system to draw load current if one uses a larger R2C2 time constant. The recommended C2 value is less than 1F. R1 and R2 can operate as a current limiter against setting cell reverse direction or for applying excess charging voltage to the IC and battery pack. Smaller R1 and R2 values may cause excessive power consumption over the specified power dissipation rating. Therefore R1+R2 should be more than 1 kW. The time constants R1C1 and R2C2 must have a relation as follows: R1C1 R2C2 If the R1C1 time constant for the Vcell pin is larger than the R2C2 time constant for the P- pin, the IC might enter a standby mode after detecting excess current. This was noted in the operating description of the current detectors.
