PMIC - Supervisors

The X40011V8-AT1 is a supervisor-type device that operates in an integrated and intelligent power management system. It is an ideal choice for many applications due to its superior control, low power consumption, and robust design. Supervisors are designed to monitor the state of a system and take appropriate actions when abnormal conditions are detected. The primary purpose of the X40011V8-AT1 is to protect the system from faults when the system is in operation or when powering-up/down.

Applications

The X40011V8-AT1 is ideal for low-power applications, such as industrial and consumer electronics. It is specially designed to protect the system against faults like under-voltage, over-voltage, over-current, over-temperature and over-power. This supervisor can provide clean, low-ripple power to the system and reset the system when it detects an any of these conditions. It is also capable of monitoring the current, voltage, and temperature levels in order to protect the system and optimize its performance.

Working Principle

The X40011V8-AT1 operates by monitoring the current, voltage, and temperature in the system. It compares these against their set points and generates a reset signal when any of the monitored conditions is outside of the programmed thresholds. The supervisor is designed to detect both slow and fast faults, and act accordingly. When an abnormal condition is detected, the supervisor can either shut down the system or cycle the power, depending on the configuration. The X40011V8-AT1 is also capable of controlling the power supply system shutdown, signalizing the start-up sequence and providing an embed I2C signal.

Integrated Features

The X40011V8-AT1 also has some integrated features that enhance the protection of the system. These include: an adjustable watch dog timer, an embedded watchdog counter with a “restart after n times” feature, an internal voltage reference, a pre-set reset level of 3.0V, over-temperature protection up to +175°C, and a power-on reset for start-up. Finally, the supervisor also has a programmable delay for startup and a clock divider that enables the frequency of the clock output.

Conclusion

In conclusion, the X40011V8-AT1 is a powerful and reliable supervisor-type device. It is ideal for low-power applications as it consumes minimal power to operate, while providing a variety of features to optimize system performance and protect against faults. This supervisor is uniquely designed to detect both slow and fast faults, and to determine the appropriate action to take according to the configured parameters. Additionally, its integrated features further enhance its protection abilities and provide added reliability.
