PMIC - Supervisors components manage the operation and reset of a system by monitoring input signals and on-chip voltage. These components help keep a system functional by detecting system failures, resetting a circuit after a predetermined trigger, ensuring that active mode current is minimized, and assisting in power sequencing. The S-80856CLNB-B7HT2G is a supervision circuit that is utilized in applications requiring a reset circuit. This article will discuss the application field and working principle of the S-80856CLNB-B7HT2G.

Application Field

The S-80856CLNB-B7HT2G device falls into the category of active low reset supervisors, or nonvolatile reset circuits. This device contains an integrated voltage detector, reset controller, and reset output, plus two active-low enable inputs for power sequencing control. The reset circuit of the S-80856CLNB-B7HT2G makes it ideally suited for embedded systems or microcontrollers, PLCs or other specialized applications that require a reset circuit. These applications include a wide range of industrial, automotive and consumer applications.

Working Principle

The S-80856CLNB-B7HT2G reset supervisor continuously monitors the supply voltage of a circuit and issues an active-low reset if the voltage drops below a predetermined operating range. The S-80856CLNB-B7HT2G includes a programmable time delay, allowing the monitor circuit to ignore false reset signals due to noise or temporary drops in voltage. The reset time delay can be adjusted between 10ms and 1210ms to accommodate various applications. The reset threshold is also user adjustable, allowing the user to choose a set voltage that is most appropriate for their application. The S-80856CLNB-B7HT2G also has the ability to provide power sequencing control through the two active-low enable inputs, EN1 and EN2. These two inputs can be used for manual or automatic control of the reset circuit.

In summary, the S-80856CLNB-B7HT2G is a nonvolatile reset circuit designed for use in embedded systems or microcontrollers, PLCs or other specialized applications. This device feature a programmable time delay for reset, an adjustable reset threshold, and two active-low enable inputs for power sequencing control. By utilizing these features, the S-80856CLNB-B7HT2G can help to maintain system functionality and prevent costly malfunctions due to unexpected system power fluctuations.
