PMIC (Power Management IC) supervisors, or reset IC (Integrated Circuit) are used in many applications, such as aerospace, military, medical, automotive, and electronics. These ICs have the capability to monitor various types of voltages, currents, and other parameters, and to take appropriate action when such parameters fall outside of their pre-defined boundaries. These ICs protect sensitive electronics from damage due to excessive current and voltage, or other abnormal conditions, and can reset the electronics to a known state in the event of a fault or system crash.The S-80816CNUA-B8BT2G is a power monitoring supervisor IC from STMicroelectronics. It is designed to monitor the power supply in a wide variety of circuit designs, including batteries, chargers, and power management systems. The S-80816CNUA-B8BT2G features an advanced voltage regulation system with four adjustable voltage thresholds, two temperature sensors, a watchdog timer, and an active comparator. The IC is designed to detect and respond to unusual supply conditions, including under-voltage, over-voltage, and over-current conditions.

The main purpose of the S-80816CNUA-B8BT2G is to protect the circuit from over-voltage or over-current conditions, which can cause damage to the components and possibly the system as a whole. It prevents the components from being over-stressed by detecting and responding to any abnormal conditions. It also helps maintain a stable power supply voltage. The four adjustable voltage thresholds and two temperature sensors allow the IC to quickly detect conditions outside of the normal range, and to take appropriate action such as shutting down the system, switching off the power supply, or triggering an alarm signal.

The IC also features a watchdog timer and an active comparator. The watchdog timer monitors the system and trigger a reset signal if there is a problem. The active comparator is used to monitor the voltage of the power supply and compare it with the reference voltage. If the reference voltage is exceeded, the active comparator will detect the fault and trigger the reset signal. This helps maintain a steady and reliable operation of the system.

The S-80816CNUA-B8BT2G is suitable for use in a variety of applications, including industrial systems, medical equipment, communications equipment, portable electronics, and automotive systems. It can be used to monitor and protect the power supply in a wide range of circuit designs ranging from switch mode power supplies and Li-Ion battery chargers to complex power management systems. The adjustable threshold levels, temperature sensors, watchdog timer, and active comparator help ensure reliable and robust operation of the system under all conditions.

The S-80816CNUA-B8BT2G is a versatile and reliable power management supervisor IC that can be used in a variety of applications. It is designed to monitor the power supply and trigger a reset signal in the event of any abnormal conditions, such as under-voltage, over-voltage, or over-current. It is suitable for use in a wide range of circuit designs, and its adjustable thresholds, temperature sensors, watchdog timer, and active comparator make it a reliable and robust power monitoring supervisor IC.
