PMIC - Supervisors

A supervisor is an integrated circuit device used to detect system signals and monitor system activity in a variety of applications. The S-80932CNPF-G82TFG supervisor is a microchip-based system designed to provide power monitoring, over-voltage protection and a low-voltage reset signal in applications requiring a reliable safety feature. This device has a wide range of applications including automotive, aviation, industrial and consumer electronics.

Application Field

The S-80932CNPF-G82TFG supervisor is commonly used in power applications where over-voltage protection, low-voltage reset and circuit protection is required. It is typically used in automotive, aviation, industrial, and consumer electronics applications, including:

• Automotive Energy Management Applications such as Vehicle Monitoring and Control
• Aviation Equipment and Instrumentation
• Industrial Process Control Systems
• Consumer Electronics such as Battery Management and Charging
• Computer and Network Security
• Medical Equipment and Instruments

Working Principle

The S-80932CNPF-G82TFG supervisor is designed to monitor an input signal and output a reset signal when the input signal drops below a pre-set value. When the input signal reaches a critical level, the reset signal is activated, allowing the system to activate the reset sequence and restore operation. The device can also provide a warning signal when the system reaches an over-voltage condition, preventing any damage that may result from over-voltage.

The supervisor monitors the input signal by comparing it to a reference signal, typically coming from a resistor-capacitor (RC) oscillator. The oscillator produces a signal at a fixed frequency and the supervisor compares it with the incoming signal, measuring the time difference between the two signals. If the input signal drops for longer than the pre-set interval, the supervisor will activate the reset signal.

The reset signal can be used to alert the system that an over-voltage or low-voltage condition has occurred and the system can take appropriate measures to protect itself against damage. The reset signal can be used to activate the system shutdown sequence, activate a fuse, or shut off all power.

The S-80932CNPF-G82TFG supervisor is also designed to provide protection against voltage and current overshoot, which can cause circuits to be destroyed. The device can detect overshoot and trip the reset signal before any damage occurs.

Conclusion

The S-80932CNPF-G82TFG supervisor is designed to provide reliable over-voltage and low-voltage protection and reset signal in automotive, aviation, industrial and consumer electronics applications. Its combination of voltage and current overshoot protection and reset signal make it an excellent choice for applications where reliable protection is required.
