Description

The MAX16033MAX16040 supervisory circuits reduce the complexity and number of components required for power-supply monitoring and battery control functions in microprocessor (P) systems. The devices significantly improve system reliability and accuracy compared  to other ICs or discrete components. The MAX16033MAX16040 provide P reset, backup-battery switchover, power-fail warning, watchdog, and chip-enable gating features.

The MAX16033MAX16040 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 (MAX16033MAX16036). Each device includes a power-fail comparator and offers an active-low pushpull reset or an active-low open-drain reset.

The MAX16033MAX16040 are available in 2mm x 2mm, 8-pin or 10-pin DFN packages and are fully specified from -40°C to +85°C.
