Functional Features

Voltage Monitoring

The TPS3306-25QDRQ1 continuously monitors the power supply voltage and compares it with the user-defined threshold levels. It generates a reset signal when the voltage crosses these thresholds, indicating an undervoltage or overvoltage condition.

Manual Reset

The device includes a manual reset input (MR) that allows users to manually trigger a reset signal, overriding the voltage monitoring function.

Adjustable Thresholds

By connecting external resistors to the threshold voltage setting pin (TH), users can adjust the voltage thresholds at which the reset signal is generated.

Power-On Reset Delay

Upon power-up, the TPS3306-25QDRQ1 provides a fixed delay before generating the first reset signal. This delay ensures stable power supply voltage during system initialization.
