Description

The HIP0060 is a 5V logic controlled Quad Low Side Power Driver. The outputs are individually protected for over-current (OC), over-temperature (OT) and over-voltage (OV). If an OC short circuit in the output load is sensed (IS) in one output power driver, that output current will be independently limited while the other outputs remain in operation. Over-current is limited by direct gate feedback. Over-voltage protection is provided by a drain-to-gate zener diode that clamps inductive switching pulses.

The HIP0060 output drivers are individually controlled through a Gate Control Latch. Temperature is sensed at each output. If a thermal fault exists, a status flag is set and the output is latched off. Open-load (OL) and over-temperature (OT) faults sets a status flag bit as diagnostic output to the SPI bus. For all fault bits (8), an ORed one-shot interrupt signal is output to the INT pin. An RST reset clears the fault flags and disables all outputs while active. The Serial Peripheral Interface (SPI) bus pins are the Serial Input (SI), Serial Output (SO), Serial Data Clock (SCK) and the Chip Select (CS).

The HIP0060 is fabricated in a Power BiMOS IC process, and is intended for use in automotive and other applications having a wide range of temperature and electrical stress conditions. HIP0060 is particularly suited for driving lamps, relays, and solenoids in applications where low operating power, high breakdown voltage, and higher output current at high temperatures is required.
