Advantages and Disadvantages

Advantages: - Efficient voltage monitoring and reset generation. - Wide operating voltage range allows compatibility with various systems. - Small package size saves board space. - Low-power consumption prolongs battery life.

Disadvantages: - Limited number of threshold voltage and timeout period options. - No built-in hysteresis feature.

Working Principles

The TLC7705QPWRG4 operates by continuously monitoring the supply voltage using an internal voltage reference. When the voltage drops below the selected threshold level, the IC generates a reset signal on the RESET pin. This signal remains active until the voltage rises above the threshold or a manual reset is applied through the MR pin. The timeout period determines how long the reset signal remains active after the voltage returns to normal.
