Information

The TCM809 is 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 μsec of VDD falling through the reset voltage threshold. RESET is maintained active for a minimum of 140 msec after VDD rises above the reset threshold. the TCM809 has an active-low RESET output. The output of the TCM809 is valid down to VDD = 1V. Both devices are available in 3-Pin SC-70 and SOT-23B packages. The TCM809 are optimized to reject fast transient glitches on the VDD line. A low supply current of 9 μA (typ., VDD = 3.3V) make these devices suitable for battery-powered applications.
