Supervisors

MaxLinear offers a line of supervisory circuits that ensure safe operating conditions for microprocessor and memory based systems. By monitoring one or more system supplies, supervisory circuits provide basic protection such as power-on reset as well as fault monitoring during power-up, power down and undervoltage (brownout) conditions. Additional functions typically include a watchdog timer, a manual reset and battery backup supply switching.
