TCM809/TCM810 is a low power system supervisor circuit designed to monitor VDD in digital systems and provide a reset signal to the host processor, when necessary. It is low power (9 µA), has a wide temperature range from -40°C to +125°C and is suitable for use in computers, embedded systems, battery-powered equipment, critical microcontroller power supply monitoring and automotive applications.
The TCM809 and TCM810 are low‑power 3‑pin microcontroller reset monitor circuits that provide precise Vpp monitoring and a push‑pull reset output. They operate without external components and are offered in SC‑70 and SOT‑23B packages.
The document lists electrical characteristics such as supply voltage range, reset timing, and current consumption, as well as typical performance graphs, packaging dimensions, and application guidelines for embedded and battery‑powered systems.
