Features

General Description

The APX1690 is a precise 9-Set over voltage protector.

The trigger voltages of IN1 to IN4 are internally set to

detect the 7.0V, 4.5V, 4.0V and 3.0V, respectively.

The trigger voltage of IN5 to IN9 can be set by using

external resistor divider with the internal reference

voltage (1.5V). The APX1690 offers 2% voltage set-

ting accuracy over temp, and an ultra low ground

current 40

µA(max). The ground current is reduced

to 30

µA(max) when an over voltage happened and

output is latched. Both complementary outputs (OUT

and OUT) are latched when an over voltage is de-

tected in either input. An external active high on re-

set pin can be used to reset the latch. A compact

package QSOP-16 is available for space saving

purpose.
