The Texas Instruments BQ25790YBGR is a highly integrated, switch-mode buck-boost battery charger designed for 1-4 cell Li-ion and Li-polymer batteries. It offers flexible control via I2C and supports autonomous operation.
Key electrical specifications include a maximum charging current of 5A with 10mA resolution, a wide input operating voltage range from 3.6V to 24V (30V absolute maximum), and a maximum battery pack voltage of 18.8V. The device features programmable switching frequencies of 750kHz and 1.5MHz, and provides high efficiency, reaching 96.5% with a 9V input at 3A charge current.
This charger supports USB Power Delivery 3.0 OTG output with a voltage range of 2.8V to 22V and current regulation up to 3.32A. It integrates essential features like input and charging current sensing, four switching MOSFETs, and a BATFET. Safety features include over-current, over-temperature, over-voltage, and short-circuit protection.
The BQ25790YBGR is supplied in a compact 56-DSBGA package suitable for surface mounting. Its operating temperature range is -40°C to 85°C.
