View All Product from Analog Devices Inc./Maxim IntegratedThe MAX6442KADJWD7+ is a family of ultra-low-power battery monitors with integrated microprocessor (µP) supervisors. These battery monitors are available with single or dual low-battery output options that signal the status of the battery—whether it's okay (enabling full system operation), low (for low-power system operation), or dead (disabling system operation). Additionally, these devices feature an independent µP supervisor that monitors VCC and provides an active-low reset output. A manual reset function is available to reset the µP with a push-button, and no external components are required.
The MAX6442KADJWD7+ is offered with several factory-trimmed low-battery threshold combinations, ideal for single-cell lithium-ion (Li+) or multicell alkaline/NiCd/NiMH applications. When the battery voltage drops below each specified low threshold, the low-battery outputs are asserted to alert the system. When the voltage rises above the specified high thresholds, the outputs are deasserted after a 150ms minimum timeout period, ensuring the voltages have stabilized before power circuitry is activated or providing microprocessor reset timing. The low and high thresholds provide hysteresis in battery-operated systems to eliminate output chattering.
The MAX6442KADJWD7+ offers factory-trimmed battery monitors with dual outputs. All battery monitors have open-drain low-battery outputs. It monitors system voltages (VCC) from 1.8V to 3.3V with seven fixed reset threshold options. Each device is offered with two minimum reset timeout periods of 150ms or 1200ms. The MAX6442KADJWD7+ is offered with a push-pull RESET output.
The MAX6441 is offered in an SOT23 package and is fully specified over a -40°C to +85°C temperature range.
