TL7702BCP

The TL7702BCP from Texas Instruments is an integrated-circuit supply-voltage supervisor. It functions as a reset controller for microcomputer and microprocessor systems, monitoring the supply voltage at the SENSE input for undervoltage conditions. When an undervoltage event occurs, the RESET and RESET outputs become active. This device features a power-on reset generator and automatic reset generation after a voltage drop. The RESET output is defined from VCC ≥ 1 V, and it includes a precision voltage sensor with a temperature-compensated voltage reference. The TL7702BCP provides true and complement reset outputs and allows for externally adjustable pulse duration. It is characterized for operation from 0°C to 70°C and comes in an 8-PDIP package suitable for through-hole mounting.

Key electrical specifications include a threshold voltage of 2.53V (typical), monitoring a single voltage supply. The reset output can be active high or active low, with complementary outputs. The typical propagation delay for the reset timeout is 270ns. This supervisor is designed for applications requiring reliable power monitoring and system reset functions, such as in wireless communication systems, factory automation, and computer systems.
