Quad Power Drivers with
Serial Diagnostic Interface
Description
The HIP0082 and HIP0084 Quad Power Drivers contain four
individually protected NDMOS transistor switches to drive
inductive and resistive loads such as: fuel injectors, relays,
solenoids, etc. The outputs are low-side switches driven by
active-low CMOS logic inputs. Each output is protected
against excessive current due to a short-circuit. Internal
drain-to-gate zener diodes provide output clamping for over
voltage. An integrated charge pump allows operation from a
single 5V logic supply. Diagnostic circuits provide ground
short (SG), supply short (SC) and open load (OL) detection
for each of the four output stages and indicate over tempera-
ture. Diagnostic information may be read via a synchronous
serial interface. Six bits of write/store data sets a long or
short OL fault delay time for each output and sets Outputs 3
and 4 to a 2A or 5A current shutdown threshold. The
HIP0084 is specified with controlled slew rate switching.
Both types are fabricated in a Power BiMOS IC process and
are intended for use in automotive and other applications with a
wide range of temperature and electrical stress. They are par-
ticularly suited for driving high-current inductive loads requiring
high breakdown voltage and high output current. Both types
available in the 15 lead Power SIP or 20 lead PSOP packages
with low thermal resistance for high power applications.
