S-80854CNMC-B9FT2U

The S-80854CNMC-B9FT2U is a supervisor PMIC (Power Management Integrated Circuit) monitor and control various parameters of power supply and output circuits. The device consists of a voltage regulated voltage supervisor and a voltage regulator controller. It is designed to provide system monitoring, power control and monitoring, and input/output (I/O) protection functions, making it suitable for use in a variety of applications.

The voltage regulator controller section of the S-80854CNMC-B9FT2U comprises of a low-dropout (LDO) regulator with a control output, which can be used to monitor system power voltage, control power supply voltage and regulate output voltage within a predefined range. This is combined with an open drain configuration, which allows for either a low standby power supply or a high standby power supply. The device utilizes a dual-timer architecture, which allows the user to program a detection window and selection of delay time. This makes the S-80854CNMC-B9FT2U ideal for applications such as surveillance and security systems.

The voltage regulator controller of the S-80854CNMC-B9FT2U contains a high-speed internal reset system which is triggered when the voltage regulator output voltage drops below the user-defined threshold, producing a reset signal. This reset signal can be used to initiate system shut down in the event of brownout or overvoltage conditions. Additionally, the device includes an LED indicator that flashes, alerting a user to a system fault situation. The device also has an internal temperature sensor which monitors the ambient temperature and can be used to initiate either forced shutdown or safe power down operations.

The voltage supervisor section of the S-80854CNMC-B9FT2U is designed to provide supply and output voltage monitoring. This ensures the circuit operates within the specified range and acts as a failsafe in the event of an overvoltage or brownout conditions. The voltage supervisor utilizes a dual-channel, low-voltage detection (LVD) system to detect the output voltage falling below the user-specified threshold, which allows for protection against false reset and reset signal glitching.

The S-80854CNMC-B9FT2U provides a host of features including low-power sleep modes, adjustable low-voltage detection thresholds, internal overtemperature protection, variable gain and response time settings, adjustable reset input thresholds and internal programmable selectable timeout. These features, combined with its low power consumption and flexibility, make the S-80854CNMC-B9FT2U an ideal supervisory PMIC for a variety of applications such as smart home appliances, as well as industrial, automotive, network and reference designs.

In summary, the S-80854CNMC-B9FT2U is a highly flexible, low-power monitor and control device offering a wide range of features and protection. Its ease of integration and configurability make it ideal for a variety of applications and make it an excellent choice for designers looking for a comprehensive supervisory PMIC.
