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 overtemperature or low fluid 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.
