Maxim introduces the MAX6854-MAX6869, nanopower microprocessor supervisory circuits with optional manual reset and/or a watchdog timer. With 170 nA (typ) supply-current, these devices are suitable for portable applications such as glucose meters, cell phones, PDAs, pagers, and MP3 players. The device monitor system voltages for undervoltage conditions. Each device is offered with reset thresholds from 1.6 V to 4.6 V in approximately 100 mV increments. Reset timeout periods are available from 10 ms to 1200 ms (min). These devices are offered with active-low push-pull, active-high push-pull, or active-low open-drain outputs.
