HIP0082AB

Description

The HIP0082 and HIP0084 Quad Power Drivers contain four individually protected NDMOS transistor switches to drive inductive and resistive loads such as: fuel injectors, relays, solenoids, etc. The outputs are low-side switches driven by active-low CMOS logic inputs. Each output is protected against excessive current due to a short-circuit. Internal drain-to-gate zener diodes provide output clamping for over voltage. An integrated charge pump allows operation from a single 5V logic supply. Diagnostic circuits provide ground short (SG), supply short (SC) and open load (OL) detection for each of the four output stages and indicate over temperature. Diagnostic information may be read via a synchronous serial interface. Six bits of write/store data sets a long or short OL fault delay time for each output and sets Outputs 3 and 4 to a 2A or 5A current shutdown threshold. The HIP0084 is specified with controlled slew rate switching.
Both types are fabricated in a Power BiMOS IC process and are intended for use in automotive and other applications with a wide range of temperature and electrical stress. They are particularly suited for driving high-current inductive loads requiring high breakdown voltage and high output current. Both types available in the 15 lead Power SIP or 20 lead PSOP packages with low thermal resistance for high power applications.
