Working Principles

The TLC7733IPWR is a voltage supervisor IC that monitors the power supply voltage and generates a reset signal when the voltage falls below a certain threshold. It operates based on a precision reference voltage and a comparator circuit. The threshold voltage can be selected using the TH pin, allowing flexibility in different applications. The delay time for the reset signal can be adjusted using an external capacitor connected to the CT pin. The IC also provides a manual reset option through the MR pin.
