Working Principles

The TLC7701MDREP is a voltage supervisor IC that monitors the supply voltage of a system. It compares the supply voltage with a programmable threshold voltage and generates a reset signal when the supply voltage falls below the threshold. The delay time between the supply voltage dropping below the threshold and the reset signal being asserted can be programmed using an external capacitor.

The IC operates with low quiescent current, making it suitable for battery-powered applications. It provides precise voltage threshold detection, ensuring accurate monitoring of the supply voltage. The manual reset input allows immediate system reset when required. The Power-On Reset output ensures proper initialization of the system during power-up.
