MAX16038
MAX16038 is Low-Power Battery Backup Circuits manufactured by Maxim Integrated.
- Part of the MAX16040 comparator family.
- Part of the MAX16040 comparator family.
Description
The MAX16033- MAX16040 supervisory circuits reduce the plexity and number of ponents required for power-supply monitoring and battery control functions in microprocessor (µP) systems. The devices significantly improve system reliability and accuracy pared to other ICs or discrete ponents. The MAX16033- MAX16040 provide µP reset, backup-bat.. tery switchover, power-fail warning, watchdog, and chip-enable gating 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 parator and offers an active-low pushpull reset or an active-low open-drain reset. The MAX16033- MAX16040 are available in 2mm x 2mm, 8-pin or 10-pin µDFN packages and are fully specified from -40°C to +85°C.
