Description

The HIP0050 is a logic controlled, eight channel Octal Low Side
Power Driver. As shown in the block diagram, the outputs are con­trolled via the serial data interface which allows the data to be
shifted out, allowing control of other cascaded serial devices. If an
Over-Current (OC) short circuit exists in one output, it may be inde­pendently shutdown while the other outputs remain in operation.
When a shorted output is latched off, it may be turned back on
when the next serial input data is latched. A fault flag (

FLT) is set to
a low status to indicate current-limited shutdown. The outputs are
independently latched off when an OC fault is detected. The fault
latch is cleared on the next data strobe. Over-Temperature (OT)
shutdown is provided with hysteresis to force global shutdown of
all output drivers. Shutdown is maintained until the on-chip temper­ature falls below the minimum hysteresis threshold point.

The HIP0050 is fabricated in a Power B iMOS 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, displays, relays, and solenoids in
applications where low operating power, high breakdown voltage,
and high output current at high temperature is required. Higher
current needs can be met by paralleling adjacent output drivers
