1 / 75 page  MPF42791 2 to 16 Stacked Cells Battery Pack Fuel Gauge with Resistance Detection and Thermal Model MPF42791 Rev. 1.0 MonolithicPower.com 1 9/19/2022 MPS Proprietary Information. Patent Protected. Unauthorized Photocopy and Duplication Prohibited. © 2022 MPS. All Rights Reserved. DESCRIPTION The MPF42791 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. When paired with an MP279x battery monitor, the MPF42791 can achieve SOC accuracy within 2.5% across the temperature range. The MPF42791 can also be paired with other analog front-end (AFE) or battery stack monitors. The 400kHz I2C interface provides standard, robust communication. The 5-level LED drivers provide a simple, cost-effective charge level indicator for the device. The MPF42791 is available in a TQFN-32 (4mmx4mm) package.
