MPF42790

The MPF42790 is a drop-in solution to provide comprehensive status information on lithium-ion battery strings up to 16 series cells. The MPF42790 estimates the internal state-of-charge (SOC) and state-of-health (SOH) for each cell, as well as the full pack. The MPF42790 also determines remaining runtime, charge time, and instantaneous available power. On-board memory enables the lifetime logging of key parameters.

The MPF42790 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 MPF42790 can achieve SOC accuracy within 3%. The MPF42790 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 MPF42790 is available in a TQFN-32 (4mmx4mm) package.
