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-ofcharge
(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.
