Working Principles

The LTC2964CUDC#TRPBF is a power supply monitor IC that operates by comparing the monitored voltages with programmable threshold levels. It continuously measures the voltages at the TH pins and compares them to the corresponding threshold voltages set by the user. If any of the monitored voltages fall outside the programmed range, the IC generates an active-low reset signal on the RESET pin.

The reset timeout period can be adjusted using external capacitors connected to the MR pin. This allows the system to have a flexible response time before generating the reset signal. The fault output (FLT) indicates when any of the monitored voltages are outside the programmed threshold range.
