The charge current is set with an external resistor; the timer is also programmable, giving the designer control over the charge profile without firmware overhead. Input supply maximum is 6.4 V, which provides headroom for USB bus voltage and includes over-voltage protection that shuts down the charger if the input exceeds the safe limit. ## Protection set and thermal range Integrated fault protection covers over-temperature, over-voltage, reverse current, and short circuit — this reduces external monitoring circuitry and simplifies the BOM for a portable device charger block. Cut Tape works for prototyping or low-volume builds.","metaTitle":"BQ24073RGTR Li-Ion Battery Charger IC – Texas Instruments","metaDescription":"Texas Instruments BQ24073RGTR single-cell Li-Ion/Li-Po charger IC.
