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 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 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.
