PMIC supervisors are integrated circuits (ICs) that monitor and protect the power management system. They provide microprocessor reset and power supply monitoring functions, helping to ensure the robust and reliable operation of microprocessor-based systems. The S-80946CNPF-G9GTFG is a PMIC supervisor used for providing protection functions for microprocessor-based systems and embedded systems.

S-80946CNPF-G9GTFG features integrated push-pull driver outputs, which can be directly driven by a low voltage power transistor. This eliminates the need for additional pull-ups and external pull-down resistors and simplifies circuit design. The S-80946CNPF-G9GTFG also features an on-die temperature sensor Monitor (TMON) to provide microprocessor reset interrupt and temperature monitoring through an I2C bus interface.

The S-80946CNPF-G9GTFG is designed to monitor the power supply and reset the microprocessor during power supply malfunctions. The chip also provides status indicators for inputs, such as over-voltage, under-voltage, power good, and high temperature. These indicators allow the microprocessor to monitor and adjust the system supply level and reset the microprocessor automatically when power supply voltage is abnormal.

It is suitable for use in a wide range of microprocessor- and application-level protection system designs. The chip’s low quiescent current consumption and low operating voltage make it an attractive option for portable products and battery-powered systems. It also features a guardrail reset protection circuit that guards against reset glitches and prevents system overstressing.

In summary, the S-80946CNPF-G9GTFG is a PMIC supervisor designed for microprocessor-based systems and embedded systems. It provides push-pull driver outputs, temperature monitoring, power supply monitoring, and reset functions. Its low power consumption and low voltage operation make it suitable for battery-powered applications. As a result, it is an attractive option for a wide range of protection system designs.
