Disadvantages: - Limited threshold voltage options - Single-channel monitoring (not suitable for multi-voltage systems)

Working Principles

The TPS3813I50QDBVRQ1 operates by comparing the monitored voltage with a pre-set threshold voltage. When the monitored voltage falls below the threshold, the IC asserts the reset output, initiating a system reset. The device incorporates hysteresis to prevent false triggering caused by voltage fluctuations or noise.
