Power management integrated circuits (PMICs) are essential devices to ensure that the power circuits of an electronic device function properly and that they support efficient power management. Supervisors, or System Monitors, are a subset of PMICs that specialize in monitoring system parameters such as temperature, voltage, and current and providing system reset signals when system parameters go out of range. The S-80843CNNB-B84T2U, manufactured by ON Semiconductor, is a 3.2V to 6.2V micro-power supervisor PMIC. This device provides an integrated undervoltage lockout circuit, reset generation circuit and a system reset signal.

The S-80843CNNB-B84T2U has applications in a variety of electronic systems and is commonly used in automotive and industrial applications. In automotive applications, the S-80843CNNB-B84T2U is typically used to regulate system power and monitor high voltage power rails. In industrial applications, the device is used to monitor battery and power management systems. The device can also be used in consumer applications such as computers, smartphones and tablets, where it is used to monitor system power, voltage and temperature.

The S-80843CNNB-B84T2U is designed to provide system reset signals when the monitored output voltage or temperature is below the specified thresholds. The device consists of an under voltage reset circuit, an over voltage reset circuit, an overtemperature latch reset circuit and a watchdog timer reset circuit. The reset generation circuit provides an output reset signal if the monitored output voltage or temperature drops below the specified thresholds. The under voltage reset circuit monitors the input voltage and generates an output reset signal if the input voltage drops below the preset threshold. The over voltage reset circuit monitors the output voltage and generates an output reset signal if the output voltage exceeds the preset threshold. The overtemperature latch reset circuit generates an output reset signal when the temperature exceeds the preset threshold. The watchdog timer reset circuit generates an output reset signal at a preset time interval.

The S-80843CNNB-B84T2U offers several features that make it ideal for use in automotive, industrial and consumer applications. The device offers an extremely low quiescent current of less than 1.0µA, enabling it to be used in battery-operated devices. The device also has a wide supply voltage range of 3.2V to 6.2V, making it suitable for use in a variety of applications. Additionally, the device offers several protection features, such as overtemperature and undervoltage protection, to ensure system reliability. Finally, the device provides a low voltage, low power reset signal, which is ideal for use in low power systems.

In summary, the S-80843CNNB-B84T2U is a micro-power supervisor PMIC manufactured by ON Semiconductor. This device is ideal for use in automotive, industrial and consumer applications, where its low quiescent current, wide supply voltage range and low power reset signal make it an ideal choice for power management. Additionally, the device offers protection features such as overtemperature and undervoltage protection, making it a reliable choice for any system.
