HIP0063
PRELIMINARY
October 1995
Hex Low Side MOSFET Driver with Serial or
Parallel Interface and Diagnostic Fault Control
Description
The HIP0063 is a logic controlled, six channel Low Side Power Driver. As
shown in the Block Diagram, the outputs are controlled via the serial data
interface or, by user option, each output may be independently controlled
from the respective parallel input. In addition, PWM logic switching control
(HLOS) may be directly applied to channels 0 and 1 in parallel, or channels 4
and 5 in parallel.
Output fault conditions may be detected as an output load short to supply
when the output is ON or as an open load/ground short when the output is
OFF. If an over-current short exists at one output, gate drive goes to a low
duty cycle mode. It will remain in the low duty cycle mode until switched off or
the fault is cleared. Fault bits are sent to a fault register to indicate which
channel is at fault. The fault bits are indicated by a logic one and is internally
latched when CS goes low. A fault bit will return to zero when the fault disap-
pears. Either an 8-bit or 16-bit SPI communication mode may be used. Refer
to the application section for bit control information.
Over-voltage shutdown protection for all outputs will occur when V
PWR
(Battery/
MOSFET Supply) exceeds 35V typical. When V
CC
is less than 3.5V, gate drive
is switched off. The input and gate control logic is fully function when the V
CC
supply is greater than 4V typical. The HIP0063 has an internal drain-to-gate
zener which is used to voltage clamp the output drain-to-source voltage of the
MOSFET.
The HIP0063 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 well suited for MOSFET con-
trol in circuits driving lamps, displays, relays, and solenoids in applications
requiring low operating power.
