MPF42791DRT-0B-0000-P

MPF42791 is a 2 to 16 stacked cells battery pack fuel gauge with resistance detection and thermal model. It is a drop-in solution to provide comprehensive status information on lithium-ion battery strings up to 16 series cells. The MPF42791 estimates the internal state-of-charge (SOC) and state-of-health (SOH) for each cell, as well as the full pack. The MPF42791 also determines impedance, remaining runtime, charge time, and instantaneous available power. On-board memory enables the lifetime logging of key parameters. The MPF42791 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. Applications include light EVs: scooters, bikes, and golf carts, energy storage: uninterruptable power supplies (UPS) and renewable energy, industrial robots, floor cleaners, and forklifts, cordless tools and gardening equipment.
