The from Products is a low voltage, µP supervisor with power fail in/out, manual reset and watchdog timer in 8 pin SOT-23 package. It reduces the complexity and components required to monitor power supply functions in µP systems. It provides four functions such as, a reset output during power-up, power-down and brownout conditions, an independent watchdog output that goes low if the watchdog input has not been toggled within 1.6s, a 0.62V threshold detector for power fail warning and an active-low manual reset input. MAX6705A monitors a single-supply voltage to drive a single reset output and include an independent adjustable power-fail-in/power-fail-out comparator, a manual reset input and a watchdog timer with an independent output. It is used in computers, controllers, intelligent instruments, critical µP power monitoring, white goods, networking and telecommunications applications.
