performance and environmental limits.
The TLC77xx family of micropower supply voltage supervisors provide reset control, primarily in microcomputer
and microprocessor systems.
During power-on, RESET is asserted when VDD reaches 1 V. After minimum VDD (≥ 2 V) is established, the
circuit monitors SENSE voltage and keeps the reset outputs active as long as SENSE voltage (VI(SENSE))
remains below the threshold voltage. An internal timer delays return of the output to the inactive state to ensure
proper system reset. The delay time (td) is determined by an external capacitor:
td = 2.1 × 10

× C

Where
CT is in farads
td is in seconds
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 and the delay
time (td) has expired.
