HIP0081

DATASHEET HIP0080, HIP0081 Quad Inverting Power Drivers with Serial Diagnostic Interface FN3018 Rev 5.00 November 2000 The HIP0080/0081 Quad Power Drivers contain four individually protected NDMOS power output transistor switches to drive inductive and resistive loads such as: relays, solenoids, injectors, AC and DC motors, heaters and incandescent lamp displays. The 4 Power Drivers are low-side switches driven by CMOS logic input control stages. Each Output Power Driver is protected against over-current, over-temperature and over-voltage. An internal drain-to-gate zener diode provides the clamping protection for over-voltage. Diagnostic circuits provide ground short, supply short, open load and thermal overload detection for each of the 4 output stages. Each of the 4 input drivers and their respective diagnostic filters are controlled by one ENABLE input. The inputs are CMOS logic compatible and individually control the output drivers with an active high state for turnon. All other control inputs are active high with the exception of the Chip Select (CS) which is active low. The DATAIN (DI) and DATAOUT (DO) are positive logic and the Clock (CLK) input for the Serial Interface is active on the rising edge of the CLK pulse. All Inputs except the HIP0080 ENABLE have a nominal level of hysteresis. IN1, IN2, IN3, IN4 and ENABLE have pull-down resistors of approximately 100k. This switches off any channel that has an unterminated input. Filters are used on the outputs of the f...
