It accepts power from a USB port or a regulated 5V supply, with a maximum input voltage of 6.5V. The charge current is programmable up to 500 mA, and the battery termination voltage is fixed at 4.2V. The device integrates over-temperature fault protection and programmable charge-current and charge-timer features. ## Charge current and termination voltage Maximum charge current is 500 mA, set by an external resistor. This ceiling suits small-form-factor batteries in wearables, IoT sensors, or handheld instruments where charge time is secondary to thermal management. The 4.2V battery pack voltage is the standard termination for single-cell Li-Ion and Li-Polymer cells. The constant-current / constant-voltage (CC/CV) profile is typical for linear chargers: the current is regulated until the battery reaches 4.2V, then the voltage is held while the current tapers. The programmable timer provides a safety timeout if the battery does not reach full charge within the set window. ## Active production and package options The device is supplied in Tape & Reel (TR) packaging, in a 10-VFDFN Exposed Pad package (10-VSON, 3x3 mm). Surface-mount assembly is standard.","metaTitle":"BQ24025DRCRG4 – TI bqTINY-II Li-Ion Charger, 500 mA, USB","metaDescription":"Texas Instruments BQ24025DRCRG4 single-cell Li-Ion/Polymer charger, 500 mA max, USB interface, 4.2V termination, -40°C to 125°C, 10-VSON.
