The MPF42790DRT-0B-0000-Z from Monolithic Power Systems is a Battery Pack Fuel Gauge IC that has been designed to provide comprehensive status information on Lithium-ion battery strings stacking between 2 to 16 series cells. It requires an input voltage of 3 - 3.6 V. This battery management IC estimates the internal state of charge (SOC) and state of health (SOH) of each cell and pack (containing multiple cells). It also determines the remaining runtime, charge time, and instantaneous available power. This IC supports adaptive learning and can be enabled to refine initial charge/discharge settings and update the SOH of individual cells to track degradation. It connects to a host microcontroller to periodically update the input parameters of fuel gauge and synchronize the input data to the execution time of the fuel gauge.

This battery pack IC supports few basic configurations to setup and advanced configuration capabilities that can fine-tune the device for specific applications. It can achieve an accuracy within 3% when paired with an MP279x battery monitor. This IC includes I2C serial interfaces (up to 400 kHz) for standard, robust communication with external devices such as microcontrollers or analog front-ends (AFE). It integrates 5-level LED drivers that provide simple, cost-effective charge level indications for the device. This battery pack is available in a surface-mount package that measures 4 x 4 mm and is ideal for light EV: scooters, bikes, and golf carts, energy storage, industrial robots, floor planners, and cordless equipment applications.
