The S-80944CNNB-G9ET2G is a member of the supervisory family of PMIC (Power Management IC), a type of integrated circuit that manages all the power and power related signals, often in a system. PMIC are used in portable systems and appliances, including, but not limited to, laptop computers, mobile phones, cellular base stations, and other low power portable systems.

The S-80944CNNB-G9ET2G is a low power supervisory device with integrated overvoltage, overcurrent, and reverse current protection. It is used in many portable systems and devices, and offers many improvements over earlier versions.

The S-80944CNNB-G9ET2G is designed to provide reliable overvoltage, overcurrent and reverse current protection for a wide range of portable systems and appliances. It integrates several voltage and current protection functions, including dual voltage and current monitoring, open-drain overvoltage and overcurrent protection, reverse current protection, and low-side power and reset functions.

The S-80944CNNB-G9ET2G includes integrated overvoltage protection, which will trigger a reset if the system voltage exceeds a certain preset threshold. The overvoltage protection is also designed to be non-latching, meaning it will reset the system when the voltage levels return to normal.

In addition to overvoltage protection, the S-80944CNNB-G9ET2G also offers integrated overcurrent protection. When the current flowing through the system exceeds preset limits, the S-80944CNNB-G9ET2G will trigger a reset and disable the power supply until a safe current level is reached.

Reverse current protection is also integrated into the S-80944CNNB-G9ET2G, which is designed to protect against back currents that can damage the system and components. The reverse current detection can detect back currents as low as 12mA. The integrated reset delay is also adjustable, allowing for longer wait times if needed.

In addition to the overvoltage, overcurrent and reverse current protection, the S-80944CNNB-G9ET2G also offers integrated low-side power and reset functions. The low-side power function allows the S-80944CNNB-G9ET2G to regulate the power supply and reset the system when the voltage level drops below a certain preset level. The reset function will also trigger when the voltage drops below a certain level, allowing the system to recover from power failures.

The S-80944CNNB-G9ET2G is a versatile supervisory IC that incorporates many different functions in one package. It can be used in many portable systems and appliances, offering improved protection and safety. The integrated overvoltage and overcurrent protection provide reliable protection against voltage and current levels that may damage the system, components and power supply. The integrated reverse current protection and low-side power and reset functions also provide additional safety for many portable systems and appliances.
