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.
