Maxim MAX17048X+

Монитор батареиЛитий-ионный-20°C ~ 70°C (TA)

Overview

The MAX17048/MAX17049 ICs are tiny, micropower current fuel gauges for lithium-ion (Li+) batteries in handheld and portable equipment. The MAX17048X+ operates with a single lithium cell and the MAX17049 with two lithium cells in series.

On battery insertion, the ICs debounce initial voltage measurements to improve the initial SOC estimate, thus allowing them to be located on system side. SOC, voltage, and rate information is accessed using the I2C interface. The ICs are available in a tiny 0.9mm × 1.7mm, 8-bump wafer-level package (WLP), or a 2mm × 2mm, 8-pin TDFN package.
