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

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.
