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-

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.
