PMIC - supervisors are a type of power management IC used to monitor and manage power supply voltage conditions and protect downstream logic from undershoot, overshoot, and power supply faults. The S-80929CNNB-G8ZT2G is a MICROCHIP SUPERVISOR IC with low power consumption, good noise immunity and high accuracy, making it well suited for a wide range of applications.

Application: The S-80929CNNB-G8ZT2G is typically used in applications where overvoltage and undervoltage detection and protection are needed, such as in automotive, industrial, and computing applications. It can be used in conjunction with a DC-DC converter to provide additional protection to the system power supply. It is also well suited for distributed power systems, redundant supplies, and safety-critical systems.

Working Principle: The S-80929CNNB-G8ZT2G is a low power regulator specifically designed to monitor 2 outputs (VBAT and VCC) of a DC-DC step down converter. It uses an internal bandgap circuit to monitor the inputs, and provide an overvoltage, undervoltage and power supply fault signal. This signal is used to trigger a RESET signal or control an output pin, thus protecting the system from harmful overflows and underflows.

The S-80929CNNB-G8ZT2G can be used as a stand-alone device, or as part of a larger system. It has an internal voltage reference and two oscillator frequencies which allow the user to adjust the device behavior for specific application needs. Additionally, the device can be configured in either a rising edge or falling edge reset signal mode.

The typical operating range for the S-80929CNNB-G8ZT2G is between 2.9V and 3.6V. The device also has multiple protection features, such as an adjustable overvoltage alert threshold, hysteresis control, and power-on reset. It has a maximum current draw of 2mA, making it suitable for low power applications. Finally, the device can be used in either a single-mode or dual-mode configuration, allowing it to meet the needs of a wide range of applications.

Overall, the S-80929CNNB-G8ZT2G is a robust and reliable power management IC designed for applications that require fault protection. Its low power consumption and multiple protection features make it suitable for a wide range of low power applications. Additionally, its adjustable operating parameters and multi-mode configuration allows for flexible system design.
