MAX16040 - (MAX16033 - MAX16040) Low-Power Battery Backup Circuits

General Description

The MAX16033

MAX16040 supervisory circuits reduce the complexity and number of components required for power-supply monitoring and battery control functions in microprocessor (µP) systems.

Key Features

  • The MAX16033.
  • MAX16040 operate from supply voltages up to 5.5V. The factory-set reset threshold voltage ranges from 2.32V to 4.63V. The devices feature a manual-reset input (MAX16033/MAX16037), a watchdog timer input (MAX16034/MAX16038), a battery-on output (MAX16035/MAX16039), an auxiliary adjustable reset input (MAX16036/MAX16040), and chip-enable gating (MAX16033.
  • MAX16036). Each device includes a power-fail comparator and offers an active-low pushpull reset or an active-low op.
