The is a dual-processor Supervisory Circuit with active-low push-pull output. The MicroPower supply voltage supervisor designed for circuit initialization. Its dual monitor topology is well-suited to use in DSP and processor-based systems, which often require two supply voltages, core and I/O. /RESET is asserted when the voltage at either SENSEn pin falls below its threshold voltage, VIT. When both SENSEn pins are again above their respective threshold voltages, /RESET is held low for the factory-programmed delay time 200ms typical. /RESET is also asserted if the watchdog input WDI is not toggled for more than 1.6s typical.
