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 (I
S
) 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 pro-
vided by a drain-to-gate zener diode that clamps inductive
switching pulses.
The output drivers are individually controlled through a Gate
Control Latch. Temperature is sensed at each output. If a ther-
mal 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 out-
puts 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. It
is particularly suited for driving lamps, relays, and solenoids in
applications where low operating power, high breakdown volt-
age, and higher output current at high temperatures is required.
