Power management integrated circuit (PMIC) devices are an important building block in electronic systems. This type of integrated circuit is used to deliver power and or energy management solutions in various applications. The power management solutions include power flow controllers, voltage regulators, and system power synchronizers. Supervisors are an important subset of PMIC devices. The S-80914CNMC-G8JT2G is an example of a supervisor, and this article will discuss its application and working principles.

A supervisor is an electronic device used to monitor system health and restore it to normal operation when irregularities arise. It is an active system monitoring element that continuously monitors the power supply and other system parameters for any undesired conditions. A supervisor can also be used to detect faults such as overvoltage, undervoltage, over-current, over-temperature, or short-circuit conditions. When such conditions are detected, the supervisor will act to shut down the system, thus protecting it from further damage. The S-80914CNMC-G8JT2G is a supervisor device specifically designed to monitor single voltage systems with a variety of programmable features.

The S80914CNMC-G8JT2G integrates an adjustable voltage reference circuit and an adjustable precision-bandgap which offers accuracy in the order of ±2%. It is further equipped with an integrated voltage monitor and a power fail comparator for detecting early indication of power supply failure. The device offers flexible power management and supervision through its programmable voltage threshold, delay time, reset/anti-reset pulse duration and inrush current limit levels. With its wide operating temperature range of -40ºC to 125ºC, the S-80914CNMC-G8JT2G is suitable for use in various automotive, industrial, medical, and audio-video applications.

The S-80914CNMC-G8JT2G is designed so that the system load device is connected directly to the VCC and ground pins. The voltage monitor/comparator is connected to the input pin of the supervisor. The system output is then connected to an output pin. The voltage monitor/comparator will compare the input voltage with a reference voltage and upon detection of an abnormality it will in turn drive the output pin to generate an appropriate reset or interrupt signal. This will allow external devices to be reset or powered off to prevent damage. The S-80914CNMC-G8JT2G also offers programmable features such as programmable voltage thresholds, time delays, reset/anti-reset pulse duration, and inrush current limit levels.

The S-80914CNMC-G8JT2G is a state-of-the-art supervisor device that offers superior system protection and stability in a wide range of applications. Its advantages include accuracy (±2%), wide operating temperature range (-40ºC to 125ºC), protection against over-voltage, under-voltage, over-current, over-temperature and short-circuit condition, programmable alarm thresholds, and reset/anti-reset pulse duration and inrush current limit levels. The S-80914CNMC-G8JT2G is ideal for automotive, industrial, medical and audio-video applications that require robust and highly reliable equipment.
