Disadvantages

• Limited number of threshold voltage options compared to some other voltage supervisor ICs.
• Adjustable delay requires an external capacitor, adding complexity to the circuit design.

Working Principles

The TLC7725IPWG4 operates by continuously monitoring the supply voltage using an internal voltage reference. When the voltage falls below the programmed threshold, the reset output is asserted, indicating a power failure or unstable voltage condition. The delay period can be adjusted using an external capacitor connected to the CT pins. Once the delay period elapses, the reset signal is deasserted, allowing the system to resume normal operation.
