Switching charger with USB On-the-Go for single cell Li-ion, Li-polymer, and LiFePO4 batteries

21/05/2021

The MP2733 is an I2C-controlled, narrow voltage DC (NVDC) Switching charger with USB On-the-Go (OTG) and integrated ADC for single cell Li-ion, Li-polymer, and LiFePO4 batteries. It supports 5V to 15V USB PD inputs, provides a 320mA to 4520mA programmable fast charhe current, and offers USB OTG with a 4.8V to 5.5V adjustable output. The device has robust protection features, including configurable JEITA for battery temp protection in charge mode, a battery charging safety timer, thermal regulation and shutdown, I2C watchdog monitoring, and input/system OVP. It provides BATTFET disable control to enter shipping mode, as well as system reset functionality via the DISC pin. The MP2733 is available in a QFN-26 (3.5mm x 3.5mm) package, and is ideal for applications such as smartphones, point-of-sale (POS) machines, wireless cameras, wireless speakers, and other portable devices.
