S-80853CNMC-B9ET2U

Power management integrated circuits (PMICs) are widely used in a variety of applications. These devices offer a convenient and cost-effective way to manage the power supply of a system. PMICs can range from simple components, such as voltage supervisors, to highly complex circuits with several integrated features, such as battery management units. Supervisors are a specific type of PMICs that are used in applications to detect and protect against various faults and emergencies which can cause damage to the system. S-80853CNMC-B9ET2U is an example of a supervisor PMIC.

The S-80853CNMC-B9ET2U is well-suited for applications that require protection against overvoltage and undervoltage protection, as well as power fail detection. It is also used as a sequencer and constant current source. It has a wide input voltage range of 2.8V to 20V, making it suitable for both low and high voltage systems. It also has a low quiescent current of 0.5mA, making it ideal for battery-powered applications. Additionally, it has an adjustable trip threshold, programmable output delay, and an open-drain fault output.

The working principle of S-80853CNMC-B9ET2U PMIC is fairly straightforward. It monitors the voltage level of the power supply and compares it against the user-set trip threshold. When the input voltage drops below or rises above the trip threshold, the device triggers the fault output. Depending on the configuration, this output may be set to either active-low or active-high. Additionally, the device can be configured in a sequence mode which enables it to provide a delayed output when voltage is below the trip threshold and an immediate output when it is above the trip threshold. Finally, the S-80853CNMC-B9ET2U also incorporates a constant current source which provides a stable output current regardless of changes in voltage or other environmental factors.

The S-80853CNMC-B9ET2U supervisor PMIC is designed to be robust and reliable even in harsh environments. It is also highly flexible and can be configured to fit many different application needs. It is suitable for both industrial as well as consumer and automotive grade applications. Due to its wide input voltage range, it is well-suited for applications that are powered by both AC and DC sources. Finally, the low quiescent current and programmable delay enable it to be used in battery-powered and portable applications.

In conclusion, the S-80853CNMC-B9ET2U supervisor PMIC is an ideal solution for applications that require voltage and power fail protection, sequencing, and/or current regulation. It is robust, flexible, and features an adjustable trip threshold and programmable output delay. Additionally, its low quiescent current and wide input voltage range make it suitable for battery-powered applications as well as mobile, industrial, and automotive grade applications.
