Working Principles

The TPS3702CX50DDCR operates by comparing the input voltage with a precise internal reference. When the voltage exceeds the upper or lower threshold, the device asserts the RESET pin, indicating a fault condition. The manual reset (MR) input can also be used to force a system reset. The power-on reset delay ensures that the reset signal is stable during system startup.
