The APX810S-44SR-7 from Diodes Incorporated is a 3-pin micro power voltage detector designed for microprocessor supervisory circuits. It monitors a single power supply voltage and asserts a reset signal when the VCC supply falls below a preset threshold, maintaining the reset for at least 240ms after VCC rises above the threshold.
This device features a precise voltage threshold of 4.38V, with an overvoltage threshold of 4.44V and an undervoltage threshold of 4.32V. It operates with a supply voltage range from 1V to 5.5V and consumes a low typical supply current of 10µA. The output configuration is active high, push-pull, totem pole.
Designed for reliability and low cost, the APX810S-44SR-7 eliminates the need for external components in +5V, +3.3V, +3.0V, and +2.5V powered systems. It is fully specified over temperature and guaranteed to maintain a valid reset state down to 1V.
The voltage detector is available in a compact SOT-23-3 surface mount package, making it suitable for space-constrained portable and battery-powered equipment. Applications include computers, controllers, intelligent instruments, and critical µP and µC power monitoring.
