MAX77840 3.15A Switched-Mode Charger

Analog Devices MAX77840 3.15A Switched-Mode Charger includes a ModelGauge™ m5 fuel gauge with integrated USB BC1.2 detection for Li-ion batteries and a SAFEOUT LDO. The charger integrates all switches and operates at either 4MHz or 2MHz (programmable) switching frequency, allowing the selection of small external components or achieving low heat dissipation. The MAX77840 is ideally suited for mobile point-of-sale devices, portable medical electronics, or other handheld devices. It includes the USB BC1.2 detection function to recognize common USB adapters and set the input current limit automatically. The Analog Devices MAX77840 can supply up to 1.5A OTG current with proprietary MAXOTG protection, limiting the OTG output current to prevent system voltage from collapsing under heavy OTG loads.
