Supply voltage supervisor

Supply Voltage Supervisor (SVS, or supply voltage supervisory circuit) circuits are used to monitor the supply voltage to embedded and other micro-controller systems for under voltage conditions. If an under voltage condition is detected then the supervisory circuit will reset the controller and keep it in that state as long as the under voltage condition persists.[1] This type of reset is called brown out reset. In many modern day Micro-controllers like Texas Instrument's MSP430 MCU, Brown Out Reset protection is implemented into most MSP430 devices in the case of unstable supply voltages.

Application

Supply voltage supervisors are used to protect circuitry such as MPUs, DRAM, and other devices that are easily damaged by high voltages or will operate incorrectly at low voltages. Features and functions that can be included with voltage supervisors are: [2]
