The S-80853CNPF-B9ETFU is a low-power, single-channel supervisor chip designed for use in a variety of PMIC-focused applications. The device is designed to monitor, detect and protect against over-voltage, under-voltage, temperature and current conditions, providing a high level of protection for critical system components. The device also features an on-board real-time clock, power fail flag, low battery detect LED indicator, and two input and output ports for interfacing with other devices.

The S-80853CNPF-B9ETFU is ideal for applications in which system components must be monitored and protected against over-voltage, under-voltage, temperature, and current conditions. The device can be used in industrial control systems, consumer electronics, automotive, computer, and telecommunications applications. In addition, the device can also be used in applications requiring shutdown, gain control, and self-update capabilities.

The S-80853CNPF-B9ETFU is composed of five main functional blocks: the Power Fail Flag, the Overtemperature Sensor, the Monitor and Detect Registers, the Real-Time Clock, and the Input/Output Ports. The Power Fail Flag feature is designed to monitor and detect if the system power has failed. When the power fails, the flag is set and the device can then enter a shut-down state to prevent further damage. The Overtemperature Sensor feature monitors the temperature in the system and will shut-down the system if the temperature exceeds a pre-programmed threshold.

The Monitor and Detect Registers enable the device to measure a variety of system parameters including input voltage, input current, output current, and battery voltage. These registers can also be programmed to provide a wide range of warning thresholds. If any of the monitored parameters exceed the pre-programmed thresholds, the device can enter a shut-down state to prevent further damage.

The Real-Time Clock (RTC) feature is designed to provide an accurate measure of time in the system. The RTC utilizes a 32 kHz crystal to maintain accurate time. The RTC feature can be used for power-on reset and other system tasks that require accurate timing. The RTC can also be used to provide date and time information such as the year and month in order to track system performance over time.

The Input/Output Ports provide the interface between the device and other devices such as microcontrollers. These ports can be programmed with logic levels and timeouts to enable communication between devices. The ports can also provide a wide range of digital control outputs such as pulse-width modulation (PWM) and time-delayed triggers.

The S-80853CNPF-B9ETFU offers a robust level of protection and monitoring capabilities for a wide range of applications. The device features a low power consumption for long battery life, and is designed for applications requiring low cost, high performance, and low input and output pin counts. The device is offered in 8- and 20-pin SOIC and 8- and 16-pin PDIP packages.
