Power Management Integrated Circuit (PMIC) supervisors are silicon-controlled switches capable of controlling multiple power sources reliably. The S-80819CNNB-B8ET2U is one such supervisor designed to provide overcurrent, overvoltage and temperature protection for a broad range of power circuits.

The S-80819CNNB-B8ET2U is a high performance supervisor with a wide operating voltage range of 3V to 16V, adjustable protection thresholds and a large number of configurable and adjustable output control modes. This makes the supervisor suitable for applications that require precise control of power delivery and protection, such as laptop power supplies, automotive power systems, industrial power, and telecom power supplies.

The S-80819CNNB-B8ET2U provides a variety of protections including over-current protection, over-voltage protection, under-voltage protection, and over-temperature protection. The over-current protection ensures that the current does not exceed the pre-set threshold and will either shut down the power supply or activate an alarm. The over-voltage protection limits the voltage of the power supply to a predetermined level and will either shut down the power supply or activate an alarm. The under-voltage protection is designed to monitor the voltage of the power supply and will either shut down the power supply or activate an alarm. The over-temperature protection function prevents the power supply from being used at temperatures exceeding the limit and can either shut down the power supply or activate an alarm.

The S-80819CNNB-B8ET2U also includes a built-in power-on reset circuit, which ensures safe operation by resetting the power supply whenever the voltage exceeds its maximum limits. In addition, the supervisor also includes an active current limiting circuit, which limits the current consumption depending on the over temperature, over/under voltage and over current conditions. Finally, the supervisor includes a “smart” standby mode which reduces the current consumption drastically during periods of inactivity.

The S-80819CNNB-B8ET2U is designed to be robust and reliable, and provides a wide range of protection functions for a variety of applications. It is suitable for power supplies requiring tight control of the output voltage, current and temperature parameters, and can be used in a variety of applications such as laptop power supplies, automotive power systems, industrial power, and telecom power supplies.
