Description

The TLC7733 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 TLC7733 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 * 104 * CT
Where
   CT is in farads
   td is in seconds

Except for the TLC7733, 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.
