The constant-current charge can reach 8.128 A max, fed from a supply rail up to 24 V. The SMBus interface lets the system host set charge current, voltage thresholds, and termination — the charger does not run autonomously; the firmware stack owns the charging profile.","metaTitle":"BQ25708RSNR TI Buck-Boost Battery Charger, 8.128A, 24V","metaDescription":"Texas Instruments BQ25708RSNR multi-chemistry buck-boost charger, 1-4 cells, 8.128A max, 24V supply.
