The BQ25898DYFFR from Texas Instruments is an I2C-controlled, single-cell, 4A buck battery charger with integrated power path management and USB On-the-Go (OTG) boost mode. This IC is designed for Li-Ion/Li-Polymer batteries and supports input voltages from 3.9V to 14V, with an absolute maximum rating of 22V.
Key electrical features include a maximum charge current of 4A, battery charge voltages ranging from 3.84V to 4.6V, and high charge efficiency up to 92% at 3A and 91% at 4A. The device also incorporates a selectable 500kHz/1.5MHz boost converter with up to 2.4A output, offering 94% boost efficiency at 5V/1A. It supports adjustable OTG output from 4.5V to 5.5V.
Designed for surface mount installation, the BQ25898DYFFR comes in a 42-DSBGA package. It operates within a temperature range of -40°C to 125°C (TA). The charger includes features like input current optimization (ICO), input current limit (IINDPM), input overvoltage protection (OVP), and thermal regulation for robust operation. It also supports automatic detection of USB SDP, CDP, DCP, and non-standard adapters.
Additional functionalities include BAT temperature monitoring (JEITA and hot/cold profiles), integrated ADC for system monitoring, and narrow VDC (NVDC) power path management for instant-on operation even without a battery.
