| IL33091AN, IL33091AD Powerful High-grade FET driver Description of basic functions. Developed microcircuit is a high-performance driver of high -potential power field MOS transistor control designed for use in harsh automotive switching applications requiring the capability of handling high voltages on power line attributed to transient commutation of loads in conditions of automobile exploitation. Load of microcircuit is a device on the base of MOS transistors that enables switching high current levels in automobile electrical system. Microcircuit has Fault indication output when there is short circuit in load or when load transistor current level exceeds preset value. IL33091AN IL33091AD Functions Microcircuit provides pumping of charge (on Designation of microcircuit in plastic output capacity on pin Gate of gate control)to packages: drive power MOS transistor. Input Input , IL33091AN - in DIP-package MS001BA compatible with logic levels of CMOS IL33091AD - SO-package MS-012AA microcircuits ,controls pumping of charge (switch TA = -40 / +125 in/switch off). Check of drain-source voltage is implemented package drawings (VDS) on power S transistor, detection of shorted load , presentation of error signal on pin Fault. Microcircuit has pin VT of timer, that is both input in timer window comparators and output of current square circuit, depending on r m s voltage drain-source on power MOS transistor, as power dissipated in S device is proportional to VDS2. External resistor RT and capacitor CT, connected to timer pin enable programming of timing data necessary for protection of power MOS-device. Internal circuit of stabilizer diodes with the total break down voltage of about 30V provides protection of microcircuit and power S transistor from supply voltage value to be exceeded. Activation of microcircuit Zener stabilizer diodes attributed to switching-off S transistor for the time when supply voltage value exceeded , in addition pin Fault does not change its logic state . 1 IL33091AN, IL33091AD Features. * Works with a wide variety of N-channel power field transistors * Input of control compatible with CMOS logic * Built in pumping of charge without external components * Detection and protection from shorted load and current exceeding * Failure unit reporting a FET overcurrent and shorted load condition * Possibility to connect induced loads * Forward overvoltage and battery polarity reverse protection * Extended range of operating temperatures Table of Maximum operation ratings and absolute maximum ratings .
