It provides a range of features that make it an ideal solution for these types of application. It has an input voltage range of 3V to 24V, which allows it to accommodate a variety of power sources. It also offers comprehensive protection against short circuits, over-voltage, over-temperature, and current overload, making it suitable for a variety of critical or otherwise sensitive applications. In addition, it has an integrated watchdog timer that can be used to monitor the system and detect faults before they cause any sort of damage.

The X40014V8-C is also highly programmable and configurable, allowing designers to tailor the PMIC to their exact requirements. This includes adjustable voltages, current limits, adjustment of the watchdog timer and other settings. The low quiescent current consumption of the device, combined with its low standby current, makes it an ideal choice for battery-powered applications.

Working Principle

The X40014V8-C is a type of PMIC known as a supervisor. It is designed to manage and protect the power delivered to a system by monitoring the various voltages and currents flowing through it. The device integrates a variety of features to ensure maximum safety and functionality:

• Input Voltage Monitoring: The device’s input voltage monitoring circuit monitors the input voltage and shuts down the system if it exceeds the maximum allowable level.
• Over-Current Protection: The integrated over-current protection circuit will protect the system from over-current faults by shutting down the device in the event that the current drawn exceeds the set limit.
• Over-Temperature Protection: An over-temperature protection feature will shut down the system if the temperature of the system rises beyond an acceptable threshold.
• Integrated Watchdog Timer: The integrated watchdog timer continuously monitors the system and will reset the device if it detects a fault or failure. The timer can be adjusted to suit the individual needs of the application.

The X40014V8-C is also designed to operate efficiently and reliably in a wide range of conditions. It has a low quiescent current consumption of just 100uA and a low standby current of just 200uA, making it suitable for battery-powered devices.
