Power management integrated circuits (PMICs) have been a key component in portable and embedded device designs for several decades. PMICs are used to monitor voltage levels, regulate output voltage, manage high LED current and protect circuits from high levels of input, output and battery voltages. One popular PMIC series is the S-80923CNPF-G8TTFG series.

The S-80923CNPF-G8TTFG is a supervisor IC specifically designed for modern applications. It features an advanced charging system and five output stages. The charge circuit is especially designed to be highly efficient and support both high- and low-speed charging. The five output stages allow for independently controlled voltages ranging from 1.8V to 5.5V, making it ideal for application fields where accuracy and performance are highly important.

The S-80923CNPF-G8TTFG comes with a variety of features and functions. One of its key advantages is the fact that it includes an over-temperature and over-voltage protection circuit. This circuit protects the device from electrical and thermal stressors, ensuring a high level of reliability. Additionally, the device includes a unique built-in watchdog timer. This timer is used to reset the device in case of system failure or software crash, allowing it to return to a known, working state.

The S-80923CNPF-G8TTFG is often found in applications such as Internet of Things devices, battery management systems, smart wearables, and automotive electronic systems. It is designed to serve as a power up supervisor, power down supervisor, fast charging supervisor, and power backup manager. Additionally, it can be used as a system reset supervisor, power-on reset logic circuit, programmable voltage detector, system reset control circuit and power monitoring circuit.

The working principle of the S-80923CNPF-G8TTFG is fairly straightforward. First, the device monitors the input voltage level. If the input voltage drops below the preset threshold, the device attempts to regulate the output voltage. The energy stored in its output capacitor can be used to regulate the output voltage if the input voltage drops drastically, ensuring the output voltage remains stable and within expected levels.

In addition to regulating the output voltage, the S-80923CNPF-G8TTFG can also protect the system from overvoltage, overtemperature, and overcurrent conditions. If one of these conditions occurs, the device automatically shuts off the output and resets the system. This helps maintain system integrity and adds a layer of safety against damage due to voltage fluctuations.

In conclusion, the S-80923CNPF-G8TTFG is a versatile supervisor IC designed to provide an integrated solution for portable, embedded, and automotive applications. With an integrated over-temperature and over-voltage protection circuit, built-in watchdog timer, and five output stages, this device is well-suited for a variety of applications. Its working principle is simple, using the stored energy of its output capacitor to regulate the output voltage and protect the system from voltage fluctuations.
