TECHNICAL DATA Powerful High-grade FET driver KK33091A Description of basic functions. 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. ORDERING INFORMATION KK33091AN Plastic KK33091AD SOIC TA = -40° to 125° C for all packages. Functions Microcircuit provides pumping of charge (on output capacity on pin Gate of gate control)to drive power MOS transistor. Input Input , compatible with logic levels of CMOS microcircuits ,controls pumping of charge (switch in/switch off). Check of drain-source voltage is implemented (VDS) on power МОS 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 МОS 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 МОS transistor from supply voltage value to be exceeded. Activation of microcircuit Zener stabilizer diodes attributed to switching-off МОS transistor for the time when supply voltage value exceeded , in addition pin Fault does not change its logic state . 1 KK33091A 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 .
