description

The TLC77xx family of micropower supply voltage

supervisors provide reset control, primarily in

microcomputer and microprocessor systems.

established, the circuit monitors SENSE voltage

and keeps the reset outputs active as long as

threshold voltage. An internal timer delays return

of the output to the inactive state to ensure proper

an external capacitor:

Where

Except for the TLC7701, which can be customized with two external resistors, each supervisor has a fixed

SENSE threshold voltage set by an internal voltage divider. When SENSE voltage drops below the threshold

voltage, the outputs become active and stay in that state until SENSE voltage returns above threshold voltage
