Functional Features

Power Supply Voltage Monitoring

LTC2902-2IGN#PBF continuously monitors the power supply voltage and provides a reset signal when it falls below a certain threshold.

Reset Output

The reset output of LTC2902-2IGN#PBF goes active when the power supply voltage drops below the threshold, indicating a power failure or fault condition.

Adjustable Timeout Delay

This product allows users to adjust the timeout delay for the reset signal, providing flexibility in different application scenarios.

Advantages and Disadvantages

Advantages
