HIP1031
December 1997
Half Amp High Side Driver with
Overload Protection
Description
The HIP1031 is a High Side Driver Power Integrated Circuit
designed to switch power supply voltage to an output load. It
is the equivalent of a PNP pass transistor operated as a
protected high side current switch in the saturated ON state
with low forward voltage drop at the maximum rated current. It
has low output leakage and low idle current in the OFF state.
The Functional Block Diagram for the HIP1031 shows the
protection control circuit functions of over-current, overvoltage
and over-temperature. A small metal resistor senses
overcurrent in the power supply path of the pass transistor
and load. Overvoltage detection and shutdown of the output
driver occurs when a comparator determines that the supply
voltage has exceeded a comparator reference level. Over-
temperature is sensed from a V
BE
differential sense element
that is thermally close to the output drive transistor. In addition
to the input detected overvoltage protection, negative peak
voltage of an inductive load is clamped with an internal zener
diode. An internal bandgap supply voltage source provides a
stable voltage reference over the chip operating temperature
range, providing bias and reference control for the protection
circuits.
The HIP1031 is particularly well suited for driving lamps,
relays, and solenoids in automotive and industrial control
applications where voltage and current overload protection at
high temperatures is required. The HIP1031 is supplied in a 5
lead TS-001AA Power SIP package.
