A power management/supervisory integrated circuit (PMIC/Supervisor) is a type of integrated circuit that optimizes power management and provides power control in an application. The S-80955CNPF-G9RTFU is an ideal choice for microcontroller-based system power supplies. It offers full protection for over-voltage, under-voltage, over-temperature and short-circuit, along with reverse polarity input protection.

The S-80955CNPF-G9RTFU is a 4-output low power supervisor integrated circuit (IC) providing power management and control for microcontroller-based systems with single or multiple output devices. It has a supply voltage of 2.7V to 6.5V, a maximum load current of 3.2A and on-state voltage drop of 0.35V at 3A. It can provide output voltages ranging from 0.9V to 5.5V.

The device ensures that the system\'s power supplies are up to standards and has protection against overpower, over-voltage, under-voltage, over-temperature and short-circuit. It also offers reverse polarity input protection, as well as ESD and EMF protection. In addition, it can provide accurate over-current and over-temperature protection to control the power of the circuit.

The S-80955CNPF-G9RTFU utilizes a number of analog and digital function blocks. The analog blocks are used to monitor input and output voltages, current, temperature and other system parameters for accurate power management. The digital blocks are used for monitoring, controlling and housekeeping operations in the device.

The core block in the S-80955CNPF-G9RTFU is the voltage supervisor that performs over-voltage, under-voltage, temperature and short-circuit protection. This block acts as the power supply manager that monitors input and output voltages and provides power management functions. It also provides ESD and over-current protection.

The device also includes a power-on reset (POR) function that sets the system reset signal when the input voltage reaches a certain level. The reset signal is used to reset the microcontroller to the initial state when a power failure occurs. The POR time for the S-80955CNPF-G9RTFU can be programmed by adjusting an internal resistor.

The S-80955CNPF-G9RTFU also has a wake-up function that allows the microcontroller to enter the active state without applying a reset signal. This function is activated when the input voltage reaches a certain level or when an external wake-up pin is activated.

In addition, the device has an adjustable temperature sensor that can be used to monitor the system temperature and provide over-temperature protection. The adjustable temperature range is -40°C to +105°C.

The S-80955CNPF-G9RTFU is ideal for a wide range of applications, including automotive, medical, industrial, consumer and other applications. It is available in a 4mm x 4mm, 8-pin DFN package that allows for easy-to-use implementation.

The S-80955CNPF-G9RTFU is easy to configure and offers excellent features for an efficient power management system. With its wide range of features, high accuracy and reliability, it is suitable for providing power management and control in a variety of applications.
