Protected High Side Power Switch With Transient Suppression

The HIP1090 is a Protected Power Interface Switch designed to suppress potentially damaging over-voltage transients with peak voltage source inputs ranging up to 90V in amplitude. It is designed to be operated in a hard- wired pass-thru mode or as a high side power Switch which controls the current ow through a PNP pass Transistor of the IC. In either mode The HIP1090 has a low saturated forward voltage drop. The protected load circuit is connected to the output of the IC. As such, the HIP1090 operates as a transient suppressor where the PNP drive Transistor is switched off when VIN is greater than the Over-Voltage Shut- down range of 16V to 19V. Shutdown also occurs when VIN is less than the forward turn-on threshold of approximately 2.5V, including the negative voltage range. The merits of transient suppression depend on the required integrity of the applications load elements. Instrument panel signal warning lights for critical functions such as over- temperature or low uid levels CAN be protected by the HIP1090 against high level transient voltages and double battery conditions that may potentially cause bulb burnouts. The HIP1090 may be used to protect the power supplies of small signal or Logic circuits with voltages ranging from 4V to 16V, effectively blocking higher peak voltages. The HIP1090 has internal current limiting protection in the range of 1A to 2A for short circuit to ground conditions and thermal shutdown protection when the junction temperature is greater than 150oC. It is capable of driving resistive, inductive or lamp loads (such as lamps No. 168 or 194) with minimum risk of damage under harsh environmental stress conditions. The HIP1090 is supplied in a 3 lead TO-220AB package. By Intersil Corporation
