APX1690

www.DataSheet4U.com APX1690 9-Set Over Voltage Protector Features 9-Set Voltage Monitors (4 Fixed Inputs for 7.0V, 4.5V, 4.0V and 3.0V, 5 Adjustable Inputs with 1. 5V Internal Reference) Input Voltage Range of 2~5V (Good for RTC Battery) Complementary Output to Drive 2N7002 Outputs with Latch Quiescent Supply Current : 40µA Quiescent Supply Current : 30µA When Output Latch VREF=1.5V±2.0% Over Temp 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 setting 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 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.
