Product Summary

The TLC7703QD is a micropower supply voltage supervisor. The TLC7703QD provides 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.
