Passives, or power management integrated circuits (PMICs), play a crucial role in today’s cutting-edge technology. PMICs enable power designers to quickly and reliably build a power system to manage power and eliminate system failure risks. Of all the PMICs, Supervisors are essential for power designers because their heart is to monitor, respond and protect power systems from system-level short circuits, undervoltages and other electrical conditions. A typical example of a Supervisors is S-80847CLNB-B68T2G from ON Semiconductor.

S-80847CLNB-B68T2G is a low wattage supervisor which is designed to monitor power and voltage conditions with high accuracy for a variety of system power supplies and applications. It is also compatible with industry standard 3.3V and 5V power supplies, making it suitable for a wide variety of applications. The device combines a low-power high-accuracy comparator, an internally-generated reference voltage, an oscillator, and an adjustable supervisor timer allowing the design of a complete power-supply monitoring system.

In terms of its application field, S-80847CLNB-B68T2G is most suitable for intelligent electronic devices, computer systems, AC/DC adapters, industrial controllers and smart phones. With its wide supply voltage range and precision monitoring, it will be able to prevent the power supply from short-circuiting, undervoltage and other electrical anomalies.

As for the working principle of S-80847CLNB-B68T2G, it is a two-terminal device that draws typically only microamperes of current. In normal operation, the supervisor monitors the input voltage and compares it continuously with its own voltage reference. The output is active as long as the input is within the desired range. When the input drops out of range, the supervisor stops oscillating and holds the output low, indicating an undervoltage or overvoltage condition. When the supervisor timer is used, the output remains low until the input reaches the desired level, then it resumes its normal operation.

The S-80847CLNB-B68T2G’s low power operation and low power dissipation are advantages not found in many competitive chips. Additionally, it features a wide supply voltage range for a variety of applications and a highly accurate voltage monitor for improved system power failures. In terms of form factor, it is available in a small package with multiple pins, making it suitable for space-constrained design requirements.

In summary, the S-80847CLNB-B68T2G Supervisor is a reliable and accurate monitoring device suitable for a variety of application fields. It offers a wide supply voltage range and precision monitoring, allowing it to be used in environments with various electrical conditions. With its low power operation and low power dissipation, it is an ideal solution for any power supply monitoring system.
