MAX17335X22+T

MAX17335X22+T is a 35μA IQ stand-alone charger, fuel gauge, protector, and battery internal self-discharge detection IC for 1-cell lithium-ion/polymer batteries. When a voltage source is present, the IC regulates charging by modulating the charge N-FET, using AccuCharge™ charger technology. The IC regulates charge voltage, current, and FET temperature. Stand-alone charging is supported by flexible configuration in non-volatile memory. The IC ideal diode circuit supports a quick response to system transients and adapter removal with low voltage drop across the CHG FET. Typical applications include USB PPS and direct charging, smart batteries and hybrid supercap batteries, dual screen smartphones, tablets, hearables, wearables, smartwatches, medical devices, health, fitness monitors, handheld radios, computers, accessories, home/building automation, sensors, cameras, parallel battery AR/VR systems.
