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 40µA(max). The ground current is reduced
to 30µA(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.
