The I²C interface gives the host controller programmable access to charge current, charge voltage, input current limit, and system status registers — no external potentiometers or resistor dividers for setpoint adjustment. Maximum supply voltage is 24 V, which comfortably handles common AC/DC adapters rated at 19 V or 20 V used in notebook and portable equipment designs. ## Protection and temperature grade Integrated fault protection covers over-current, over-voltage, and short-circuit conditions — these are latched protections that reduce the need for external supervisory ICs in the charging path. ## Package and thermal interface Housed in a 20-VFQFN with exposed pad (supplier package designation 20-VQFN 3.5x3.5 mm), the part requires a thermal land pattern on the PCB with vias to the ground plane to pull heat from the die during high-current charging. Surface-mount assembly with the exposed pad soldered to the PCB copper — the datasheet's recommended footprint and stencil aperture are the starting point for the thermal and electrical connection. ## Compliance and documentation The base product number BQ24735 allows cross-referencing application notes, EVM user guides, and TI's technical documentation set without tracking the full orderable code.","metaTitle":"BQ24735RGRT Texas Instruments Battery Charger IC, 1-4 Cell","metaDescription":"Active-production BQ24735RGRT from Texas Instruments.
