Microchip Technology TCM809SENB713

Description
The TCM809 and TCM810 are cost-effective system supervisor circuits designed to monitor VDD in digital systems, providing a reset signal to the host processor when necessary. No external components are required.
The RESET output is typically driven active within 65 μs of VDD falling through the reset voltage threshold. RESET is maintained active for a minimum of 140 ms after VDD rises above the reset threshold.
The TCM810 has an active-high RESET output, while the TCM809 has an active-low RESET output. The output of the TCM809/TCM810 is valid down to VDD - 1V. Both devices are available in 3-Pin SC-70 and SOT-23B packages.
The TCM809/TCM810 are optimized to reject fast transient glitches on the VDD line. A low supply current of 9 μA (typ., VDD = 3.3V) makes these devices suitable for battery-powered applications.
