Precise Fuel Gauge for E-bike Batteries: MPF4279x
High State-of-Charge Accuracy Ensures Longer Battery-Lifetime
The MPF42790 from MPS 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 and also determines remaining runtime, charge time and instantaneous available power. On-board memory enables the lifetime logging of key parameters.
Fine-Tuning the Device for Specific Applications
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 of 2,5%. It can also be paired with other analog front-end (AFE) or battery stack monitors. The 400kHz I2C interface ensures 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 (4x4mm) package.
