Power management integrated circuits (PMICs) are one of the most common types of integrated circuits used in computing and embedded systems. PMICs are used to maximize power efficiency in the design of computer systems and related application processes. Supervisors, or “supervision ICs,” are a type of PMICs that monitor power supply voltage levels and trigger the reset lines of associated system processor or memory when supply voltages exceed a specified level.

The S-80942CLMC-G7CT2U is a Supervisors PMIC with an integrated voltage detector and watchdog timer. It is designed to provide a robust, cost-effective reset solution for microcontrollers, CPUs, and other electronic components. The device features an adjustable threshold voltage up to 5.5 volts and is capable of using a selectable trip current to detect faults. The integrated watchdog timer is a window-type timer with adjustable reset time and time-out intervals.

The S-80942CLMC-G7CT2U is used in a variety of application fields, including communications, industrial control, automotive, and consumer applications. The low power consumption of the device ensures efficient power consumption in battery-operated devices and applications. The device also provides temperature compensation and hysteresis built-in to ensure reliable and accurate voltage detection.

The working principle of the S-80942CLMC-G7CT2U is based on charging two capacitors through two different resistors. When the voltage across the two capacitors exceeds the threshold voltage, the output of the device is asserted and the reset line of the associated system processor or memory is triggered. In addition, the watchdog timer is used to reset the system if the system fails to reset within a certain time period. The threshold voltage, trip current, reset time, and time-out intervals are all configurable by the system designer.

The S-80942CLMC-G7CT2U is an ideal choice for applications requiring reliable reset solutions. Its small package size allows for easy integration into the design of any system. Additionally, the low power consumption of the device ensures its use in battery-operated applications. The device’s adjustable threshold voltage, multiple selectable trip current levels, and configurable reset times and time-out intervals make it an excellent choice for various applications.
