Product Description
MPF42791DRT Integrated Circuit Chip
2 To 16 Stacked Cells Battery Pack Fuel Gauge IC TQFN32
The MPF42791DRT is a 2 to 16 stacked cells battery pack fuel gauge with resistance detection and thermal model. This drop-in solution provides comprehensive status information on lithium-ion battery strings up to 16 series cells. The IC estimates internal state-of-charge (SOC) and state-of-health (SOH) for each cell and the full pack, while also determining impedance, remaining runtime, charge time, and instantaneous available power. On-board memory enables lifetime logging of key parameters.
