PMIC (Power Management Integrated Circuit) is a commonly used management device that consolidates power management into one integrated circuit (IC). Power management refers to a range of activities and processes required to monitor, manage and regulate the power used by a device or system. It involves the efficient distribution, management and monitoring of power resources, thus ensuring that the device or system receives the required power and operates within specified environmental and safety parameters. Supervisors are an important part of PMICs that ensure the safety of these devices and systems. The X40435S14-B is an example of a PMIC supervisor.

The X40435S14-B is a low-cost supervisor from Xicor. It is a 4-pin device that provides supply voltage monitoring and over-temperature protection. It features an integrated voltage supervisor and temperature sensor, as well as a configurable timeout. It also features two open-drain outputs, manual reset input and an adjustable reset threshold voltage. The device\'s supply voltage range is 0.9V to 5.5V and its temperature range is -40°C to +125°C.

The X40435S14-B\'s primary application field is in configurable power management systems.
