MPF42792 is a 2 to 16 stacked cells battery pack fuel gauge. It is a drop-in solution to provide comprehensive status information on lithium-ion battery strings up to 16 series cells. It estimates the internal state-of charge (SOC) and state-of-health (SOH) for each cell, as well as the full pack. MPF42792 also determines remaining runtime, charge time, and instantaneous available power. On-board memory enables the lifetime logging of key parameters. It is simple to use and supports a variety of lithium cell chemistries and cell sizes. A few basic configurations allow for quick set-up, and advanced configuration capabilities can fine-tune the device for specific applications. When paired with an MP279x battery monitor, the MPF42792 can achieve SOC accuracy within 3%. It can also be paired with other analogue front-end (AFE) or battery stack monitors. Applications include light EV, energy storage, industrial robots, floor cleaners, and forklifts, cordless tools and gardening equipment.
