HIP0045
1A/50V Octal Low Side Power Driver With
Serial Bus Control and Fault Protection
The HIP0045 is a logic controlled, eight channel Octal Serial
Power Low Side Driver. The serial peripheral interface (SPI)
utilized by the HIP0045 is a serial synchronous bus compatible
with Harris CDP68HC05, or equivalent, microcomputers. As
shown in the Block Diagram for the HIP0045, each of the open
drain MOS Output Drivers have individual protection for over-
voltage and over-current. Each output channel has separate
output latch control with fault unlatch and diagnostic or status
feedback. Under normal ON conditions, each output driver is in
a low voltage, high current state of saturated turn-on.
Comparators in the diagnostic circuitry monitor the output
drivers to determine if an out of saturation condition exists. If a
fault is sensed, the respective output driver for Channels 0 - 5
have overcurrent latch-off. Channels 6 and 7 are configured for
lamp drivers and have current limiting with over-temperature
latch-off. Channels 0 and 1 have direct parallel drive control for
PWM applications and are ORed with the SPI Bus control. All
channels are SPI Bus controlled and sense the output states
for diagnostic feedback.
The HIP0045 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 relays,
solenoids and lamps in applications where low standby
power, high operating voltage, and high output current in
high ambient temperature conditions is required.
The HIP0045 is in a 20 lead plastic Power SOP (PSOP)
Package with an integral copper ‘slug’ to conduct heat directly
to a PCB interface or heat sink on the bottom of the package.
