Power management integrated circuit (PMIC) are semiconductor integrated circuit components used to manage the flow of power and overall system power in electronic device. PMIC-Supervisor is a subcategory of PMIC devices that regulate the power supply of their host processor and other components in run-time and standby mode. The S-80811CNPF-B9PTFG is a PMIC-Supervisor designed by Renesas Electronics Corporation. It is a low-power, feature-rich PMIC device that provides power supply voltage supervision and control for a wide range of embedded applications.

The S-80811CNPF-B9PTFG PMIC-Supervisor consists of four key components: voltage regulator, voltage supervisor, watchdog timer and charge pump generator. The voltage regulator circuitry of the S-80811CNPF-B9PTFG is capable of delivering stable output voltages from 1.2 to 3.3 Volts. The embedded regulator can be powered from an external supply source or from an internal back-up battery, or both. It also features an adjustable regulator voltage limit, an adjustable over-current limit and a VDDM memory voltage output.

The voltage supervisor monitors the system supply voltage and will send an interrupt signal to the microcontroller in case of an under-voltage or an over-voltage anomaly. It also provides an internal voltage reference of 1.213V that can be used to detect brown-out conditions. The watchdog timer is responsible for resetting the system in case of a critical error and can be programmed to suit the specific application. Finally, the charge pump generator provides a 9V output signal that can be used to power memory devices in low-power mode.

In addition to the above building blocks, the S-80811CNPF-B9PTFG PMIC-Supervisor also features an I/O port diagnostics engine which helps shorten system test time. The device also supports low-voltage start-up to reduce the power consumption in standby mode and remote operation through I2C communication.

The S-80811CNPF-B9PTFG PMIC-Supervisor is well-suited for embedded applications such as residential and industrial controllers, medical and automotive instruments, industrial automation systems and any other device requiring a low-voltage, low-power, feature-rich supervisor circuit.

In conclusion, the S-80811CNPF-B9PTFG is a highly-integrated PMIC-Supervisor from Renesas Electronics Corporation that can provide the necessary voltage supervision and control in a variety of embedded applications. It boasts a wide range of features such as voltage regulation, voltage supervisor, watchdog timer, charge pump generator and I/O port diagnostics designed to enhance system security and performance.
