AAT351x series is a family of micro power μP reset devices from AnalogicTech™, with multiple threshold voltage, watchdog timeout period, reset active period and output drive configuration options, supporting a variety of applications.
The AAT351x PowerManager™ family offers micropower UP reset with watchdog timer functions for system designers. Devices are available in a 5‑pin SOT‑23 surface‑mount package and operate over a temperature range of –40 °C to +85 °C.
Key features include 32 selectable reset‑threshold voltages (2.6 V‑5.0 V), three watchdog timeout periods (6.3 ms‑1600 ms), multiple output configurations (push‑pull, open‑drain, bi‑directional, inverting/non‑inverting), and low quiescent current. Electrical characteristics such as supply current, thermal resistance, and maximum power dissipation are detailed in the datasheet.
