MAX17335 Charger/Fuel Gauge/Protector IC

Analog Devices Inc. MAX17335 AccuCharge + ModelGauge™ m5 EZ 1-Cell Charger/Fuel Gauge/Protector IC is a 35μA IQ stand-alone charger, fuel gauge, protector, and battery internal self-discharge detection IC for single-cell lithium-ion/polymer batteries. Using AccuCharge™ charger technology, the IC regulates charging by modulating the charge N-FET when a voltage source is present. The IC regulates charge voltage, current, and FET temperature. Stand-alone charging is supported by flexible configuration in nonvolatile memory. MAX17335's ideal diode circuit supports a quick response to system transients and adapter removal with low voltage drop across the CHG FET.
