The X40021S14Z-B supervisor is a programmable device that provides essential functions to ensure safe and reliable operation of complex systems. This supervisor, like all PMICs, has a wide range of applications including automotive, consumer, industrial, and medical markets, as well as aerospace, military and telecommunication. With respect to its specific application field, the X40021S14Z-B supervisor is useful for monitoring power supply sequence, monitoring and resetting system systems states, supply tracking and logic-level translation. It performs these functions using a combination of programmable settings, of which the basic working principle is described below.

Starting from a supply voltage, the supervisor is designed to delay the application of the voltage to the output until a certain setpoint is reached. This delay is chosen in order to ensure that the system has sufficient time to stabilize before being supplied with the voltage. Once the controller is stable and ready to operate, the output is applied and the supply voltage is monitored continuously in order to ensure proper operation. If any changes are detected, the supervisor will immediately shut off the output circuit, preventing damage to the system.

The X40021S14Z-B supervisor is also equipped with an over voltage protection feature that prevents the system from overcharging. If the input voltage exceeds the upper limit then the monitor will immediately shut off the output. This helps to extend the life of the system by preventing overvoltage and prolonged operation beyond recommended conditions. Additionally, a logic translation function is provided, allowing the device to accept multiple input signals from different logic families.This allows easy integration with existing circuit architectures without the need for additional components.

The X40021S14Z-B supervisor is designed to provide a reliable and dependable control loop for the monitoring of supply voltages, ensuring that common over-voltage or under-voltage conditions are avoided and system performance is maintained. In addition, the logic translation function allows simple implementation of multiple inputs from different logic families, allowing compatibility with a wide range of external systems.
