Analog Simulation - TCM809

The TCM809 and TCM810 are cost-effective system supervisor circuits designed to monitor VCC in digital systems and provide a reset signal to the host processor when necessary. No external components are required. The reset output is driven active within 20 µsec of VCC falling through the reset voltage threshold. Reset is maintained active for a minimum of 140msec after VCC rises above the reset threshold. The TCM810 has an active-high RESET output while the TCM809 has an active-low RESET output.
