MAX6442KAEJSD7+T General Description
The MAX6439–MAX6442 are a family of ultra-low-powerbattery monitors with integrated microprocessor (µP)supervisors. The battery monitors are offered with sin-gle or dual low-battery output options that can be usedto signal when the battery is OK (enabling full systemoperation), when the battery is low (for low-power sys-tem operation), and when the battery is dead (to dis-able system operation). These devices also have anindependent µP supervisor that monitors VCC and pro-vides an active-low reset output. A manual reset func-tion is available to reset the µP with a push-button. Noexternal components are required.The MAX6439–MAX6442 are offered with several facto-ry-trimmed low-battery threshold combinations ideal forsingle-cell lithium-ion (Li+) or multicell alkaline/NiCd/NiMH applications. When the battery voltage dropsbelow each specified low threshold, the low-battery out-puts are asserted to alert the system. When the voltagerises above the specified high thresholds, the outputsare deasserted after a 150ms minimum timeout period,ensuring the voltages have stabilized before power cir-cuitry is activated or providing microprocessor reset tim-ing. The low and high thresholds provide hysteresis inbattery-operated systems to eliminate output chattering.The MAX6439/MAX6440 offer factory-trimmed batterymonitors with a single output. The MAX6441/MAX6442offer factory-trimmed battery monitors with dual outputs.All battery monitors have open-drain low-battery outputs.The MAX6439–MAX6442 monitor system voltages(VCC) from 1.8V to 3.3V with seven fixed reset thresholdoptions. Each device is offered with two minimum resettimeout periods of 150ms or 1200ms. The MAX6439/MAX6441 are offered with an open-drain RESET outputand the MAX6440/MAX6442 are offered with a push-pull RESET output.The MAX6439–MAX6442 are offered in a SOT23 pack-age and are fully specified over a -40°C to +85°C temp-erature range.
