MAX6846, MAX6847, MAX6848, MAX6849 Low-Power, Adjustable Battery Monitors With Hysteresis And Integrated �P Reset

The MAX6846 MAX6847 MAX6848 MAX6849 are a family of ultra-low-power Battery Monitors with integrated Microprocessor (P) supervisors. The user-adjustable Battery Monitors are offered with single or dual low-battery output options that CAN be used to signal when the battery is OK (enabling full system operation), when the battery is low (for low-power system operation), and when the battery is dead (to disable system operation). These devices also have an independent P supervisor that monitors VCC and provides an active-low reset output. A manual reset function is available to reset the P with a pushbutton.
The MAX6846-MAX6849 are ideal for single-cell lithium-ion (Li+) or multicell alkaline/NiCd/NiMH applications. When the battery voltage drops below each adjusted low threshold, the low-battery outputs are asserted to alert the system. When the voltage rises above the adjusted 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
These devices have user-adjustable battery threshold voltages, providing a wide hysteresis range to prevent chattering that CAN result due to battery recovery after load removal. Single low-battery outputs are supplied by the MAX6846 MAX6847 and dual low-battery outputs are supplied by the MAX6848 MAX6849. All Battery Monitors have open-drain low-battery outputs. The MAX6846 MAX6847 MAX6848 MAX6849 monitor 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 MAX6846 MAX6848 are offered with an open-drain RESET-bar output and the MAX6847 MAX6849 are offered with a push-pull RESET-bar output. The MAX6846 MAX6847 MAX6848 MAX6849 are offered in a SOT23 package and are fully specified over a -40C to +85C temperature range.
