TCM809/TCM810 is a low-power power supply monitoring chip launched by Microchip. It is suitable for 2.5V, 3.0V, 3.3V, 5.0V power supplies.
The TCM809 and TCM810 are low‑power 3‑pin reset monitor ICs that supervise Vpp in digital systems and generate a reset signal when the supply voltage falls below a threshold. They operate without external components and are available in SC‑70 and SOT‑23B packages.
Key features include a 140 ms minimum reset timeout, 9 pA typical supply current, operation over a wide voltage range (+2.5 V to +5 V), and temperature ranges from –40 °C to +125 °C. The datasheet details electrical characteristics, pin functions, packaging dimensions, and application circuits.
