Description

The HIP1090 is a Protected Power Interface Switch

designed to suppress potentially damaging over-voltage

transients with peak voltage source inputs ranging up to

wired’ pass-thru mode or as a high side power switch which

controls the current ﬂow 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 V

down range of 16V to 19V. Shutdown also occurs when V

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 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.

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 150

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.
