The APR3011/2/3 is a low-power microprocessor reset circuit manufactured by ANPEC Electronics Corp. It has a working voltage range of 1.2V to 6V and a static current of less than 1.5µA, making it ideal for portable battery operated equipment. It can be used in a variety of applications, including switch-mode power supplies, computers, and portable electronic devices.
The APR3011/2/3 series are micro‑power reset circuits designed to monitor supply voltage in microprocessors and digital systems. They feature an extremely low quiescent current (typically 1.5 µA) and operate over a 1.2 V to 6 V input range, providing a reliable reset signal when the supply drops below a fixed threshold.
Three output versions are offered: APR3011 with push‑pull active‑low output, APR3012 with push‑pull active‑high output, and APR3013 with open‑drain active‑low output. The devices are supplied in SOT‑23, SOT‑23‑5, and SOT‑89 packages and include specifications for reset threshold, timeout period, and transient rejection capabilities.
