Description
The HIP1030 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.
The HIP1030 has low output leakage and low idle current in
the OFF state.
The Functional Block Diagram for the HIP1030 shows the
protection control circuit functions of over-current, overvoltage
and over-temperature. A small metal resistor senses over-
current 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 VBE differential sense element that is thermally
close to the output drive transistor. In addition to the input
detected overvoltage protection, negative peak voltage of a
switched inductive load is clamped with an internal zener diode.
An internal bandgap voltage source provides a stable voltage
reference over the operating temperature range, providing bias
and reference control for the protection circuits.
The HIP1030 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 HIP1030 is supplied in
a 5 lead TS-001AA Power SIP package.
