EM6151 - Low Power Windowed Watchdog

The EM6151 offers a high level of integration by combining voltage monitoring and software monitoring using a windowed watchdog.

A comparator monitors the voltage applied at the VIN input comparing it with an internal voltage reference VREF.

•  Low quiescent current 35 A  -40°C to +125°C temperature range  Windowed watchdog with an adjustable time windows, guaranteeing a minimum time and a maximum time between software clearing of the watchdog  Time base accuracy 8% (at 100ms)  Voltage reference accuracy 3%  Sleep mode function (V55)  Adjustable threshold voltage using external resistors  Adjustable power on reset (POR) delay using one external resistor  Open-drain active-low RESET output  Reset output guaranteed for regu.
