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 setting accuracy over temp, and an ultra low ground current  40A(max). The ground current is reduced to 30A(max) when an over voltage happened and output is latched. Both complementary outputs (OUT andOUT ) are latched when an over voltage is detected in either input. An external active high on reset pin can be used to reset the latch. A compact package QSOP-16 is available for space saving purpose.
