MAX6313UK32D3-T is a supervisory device (PMIC) developed by Maxim Integrated, mainly used to monitor and protect electronic systems from power outages. The device consists of two separate independent supervisors, one for supply voltage, and the other for reset signal. The two supervisors are connected by means of an OR gate, so that in case one or both supervisors enter a fault state, a reset signal is generated and sent to the system.

The MAX6313UK32D3-T includes two open drain outputs and two debounced push-pull outputs for manual reset and reset for power supply. The device can detect and reset any input voltage range from 2v to 18v and offers a supply voltage range from 2v to 5.5v. It has an extended temperature range of -40°C to +125°C, making it ideal for many industrial, automotive and medical applications. In addition, the device has a power-on reset (POR) with a start-up time of 400 us and a watchdog timeout period of 1.5s. For added system reliability, the device can detect an overvoltage fault and provide an early warning signal before a system reset occurs.

The MAX6313UK32D3-T device’s working principle is fairly simple. During normal operation, the device monitors the supply voltage and reset signal. If either or both of these signals exceed their preset thresholds, the device will assert a reset signal, which will reset the system. The device also includes a watchdog timer, which can be used to detect when a certain process has stalled or become stuck in a loop. If the timer expires without being reset by the user, it will assert a reset signal and reset the system.

In summary, the MAX6313UK32D3-T device is a reliable and low-cost PMIC used for monitoring and protecting electronic systems from power outages. It can detect a wide range of input voltages and supply voltages, as well as a watchdog timer. Its open drain outputs, push-pull outputs, and overvoltage detection ensure protection and peace of mind.
