The TCM809MENB713 from Microchip Technology is a cost-effective system supervisor circuit designed to monitor VDD in digital systems, providing a reset signal to the host processor when necessary. It requires no external components.
Key electrical specifications include a nominal voltage monitoring capability for supplies such as 2.5V, 3.0V, 3.3V, and 5.0V, with a specific operating voltage of 4.38V. The device provides an active-low, push-pull reset output that is maintained for a minimum of 140ms after VDD rises above the reset threshold. It operates with a low supply current of 9 µA typical at 3.3V.
This supervisor IC is available in a compact SOT-23-3 package, suitable for surface mount applications. It operates within an industrial temperature range of -40°C to +85°C.
Applications include computers, embedded systems, battery-powered equipment, and critical microcontroller power supply monitoring.
