Working Principles

The TL7702BIDRG4 operates by continuously monitoring the power supply voltage using an internal voltage reference. When the voltage falls below the set threshold, the IC generates a reset signal on the RESET pin. This signal can be used to reset microcontrollers, digital logic circuits, or other system components.

The reset threshold voltage can be adjusted by connecting an external resistor divider network to the THRES pin. The reset timeout period is set using an external capacitor connected to the RESET pin.
