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.
