HIP1030
December 1997
1A High Side Driver with Overload Protection
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.
