MAX6439UTK datasheet



The MAX6439UTK, MAX6439 Thru MAX6442 are a family of ultra-low-power battery monitors with integrated microprocessor (µP) supervisors. The 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 µP supervisor that monitors VCCand provides an active-low reset output. A manual reset function is available to reset the µP with a push-button. No external components are required.
