PMIC - Supervisors, such as STM6780VWB6F, arespecialized integrated circuits that provide total solutions for monitoring and management functions. They are responsible for monitoring power supply quality and for guarding against malfunctioning due toover-current or short circuit. STM6780VWB6F is a powermanagement and chip monitor integrated circuit (PMIC). It can monitor the supply voltage and control the bidirectional flow of power.

STM6780VWB6F is usually used in embedded systems and consumer electronic devices. It provides power shut off and power management functions to protect applications against malfunction. The circuit also helps to reduce power consumption and enhance system performance by efficiently controllingthe power supply during idle and active cycles. In addition, STM6780VWB6F can provide over-currentprotection, under-voltage protection and reverse power protection for the power supply system. The circuit is also capable of diagnosing issues; it can monitor the system status and detect over-voltage,over-temperature and fault conditions.

The operating principle of STM6780VWB6F is simple yet effective. The circuit operates in two different modes:static mode and dynamic mode. In the static mode, all the voltage levels are compared to a reference voltagelevel. If, at any point in time, the voltage level exceeds the reference voltage level, a "power-ok" signalis generated and an interrupt is sent to the microcontroller.

In the dynamic mode, the operation can be divided into two separate stages: detect and power cycle. Inthe detection stage, the chip will measure the supply voltage and determine whether the voltage is in anormal range. If the voltage is not in the normal range, an error signal will be generated and an interrupt willbe sent to the microcontroller. In the power cycle stage, the chip shuts off power and resets the system byactivating the power fail (PF) and reset (RESET) pins. This ensures that the system is correctly operating andprotected from any power-related malfunctions.

STM6780VWB6F is an ideal solution for embedded systems and consumer electronic devices. It provideshigh performance along with power reliability, over-current protection, under-voltage protection, reversepower protection and fault diagnosis, thereby reducing the system downtime. Furthermore, it can be usedfor high-voltage, high-current and high-frequency applications.
