The Diodes Incorporated APX803S-44SA-7 is a 3-pin microprocessor supervisory circuit designed to monitor power supply voltages in µP and digital systems. It provides a reliable and cost-effective solution for ensuring system stability during power-up and voltage fluctuations.
This supervisor features a precise voltage monitoring capability with a threshold of 4.38V. It asserts an active-low, open-drain reset signal when the VCC supply voltage declines below this preset threshold, maintaining the reset for a minimum of 140ms after VCC has risen above the threshold. The reset output is guaranteed to be valid even when VCC drops as low as 1V.
Designed for efficiency, the APX803S has a low supply current of 10µA (typical), making it suitable for portable and battery-powered equipment. It operates over a temperature range of -40°C to 85°C.
The APX803S-44SA-7 is supplied in a compact SOT-23-3 surface-mount package, minimizing PCB space. This component is ideal for critical µP and µC power monitoring applications in computers, controllers, and intelligent instruments.
