It terminates at 4.35 V and delivers up to 1.5 A charge current. The device integrates over-temperature, over-voltage, reverse-current, and short-circuit fault protection, which reduces the external component count for a safety-compliant charger circuit. Charge current and safety timer are programmable via external resistors, so one BOM can cover multiple cell capacities without firmware changes. ## Supply voltage and input interface Maximum supply voltage is 6.4 V, which gives headroom above the nominal 5 V USB bus and allows the charger to operate from a 5.5 V regulated rail without an external LDO. The USB interface designation means the part handles the input current negotiation and power-path management typical of USB-charged devices.","metaTitle":"BQ24078RGTT Texas Instruments Li-Ion Battery Charger IC","metaDescription":"BQ24078RGTT — TI single-cell Li-Ion charger, 1.5 A max, USB interface, 4.35 V termination, -40°C to 125°C, 16-VQFN.
