PMIC supervisors, such as the S-80958CNNB-G9UT2G, are integrated devices that provide a comprehensive range of features and functionalities to improve power systems design and operation. This PMIC is specifically designed to provide robust supervision of battery powered systems and guarantee glitch-free power up/down transitions. It integrates the necessary functions, including power-fail detection, voltage monitoring, reset protection, and power-on reset (POR) generation and timing.

The main application of the S-80958CNNB-G9UT2G is in monitoring battery level in portable electronic devices. It can be used to implement a battery farm as part of a power system, providing ideal protection against out-of-battery (OOB) condition. It can also be used to provide accurate measurement of battery cell voltage, and to monitor connector insertion/removal. Additionally, it can be used to implement a low-power hibernation mode, allowing the system to save energy until the next scheduled wake-up.

S-80958CNNB-G9UT2G offers a wide range of features for monitoring and controlling battery. Its advanced integration technology brings together several individual components into a single package, namely: power fail control, power-on reset, brown-out reset and battery monitoring. Its fault protection features include capacitive reset protection, time-out reset protection and power fault indicator. Furthermore, its programmable reset output has adjustable parameters to optimize reset polarity, delay and response type.

Besides its comprehensive feature set, the S-80958CNNB-G9UT2G offers high performance and reliable operation. It has a maximum operating temperature of 125 °C and a power supply range of 1.6V to 5.5V. Its advanced integration technology ensures that its power consumption is low. Moreover, its power up/down timing is accurately controlled with a programmable delay and a safe shutdown sequence.

The working principle of S-80958CNNB-G9UT2G involves monitoring the voltage of the included battery or the system’s power supply. If the voltage drops below a certain threshold, the device will generate a reset signal to protect the system. Additionally, if the system’s power is disconnected, it will monitor the voltage of the battery and generate a reset if the battery is too low, ensuring the safe shutdown of the system.

In summary, the S-80958CNNB-G9UT2G is a powerful PMIC supervisor designed to provide accurate and reliable battery monitoring, power-fail detection and reset protection. It boasts a wide range of features, excellent performance and low power consumption, making it an ideal choice for battery powered systems.
