The device is ROHS3 compliant, meeting current EU and global material restrictions without exemption. ## Charge current and regulation — sizing the thermal budget Maximum charge current is 500 mA, which sets the power dissipation floor for the 10-VSON exposed-pad package. Battery regulation voltage is fixed at 4.2 V, the standard termination for single-cell Li-Ion and Li-Polymer. No external resistor divider sets this voltage; the charger terminates when the cell reaches 4.2 V and the current tapers. ## USB interface and programmable features The USB interface allows direct connection to a USB port or a 5 V wall adapter. Input supply maximum is 6.5 V — a 5 V USB rail with ±10% tolerance is safe, but a 5% margin is recommended to avoid the 6.5 V absolute maximum. Charge current and charge timer are programmable via external resistors and a capacitor. The timer provides a safety timeout; if the battery does not reach the regulation voltage within the programmed window, the charger faults and signals the host. ## Package and thermal — layout checklist The BQ24020DRCR is supplied in a 10-VFDFN with exposed pad, also designated as 10-VSON (3x3). ## Fault protection — over-temperature shutdown Built-in over-temperature protection disables the charger if the die temperature exceeds the thermal shutdown threshold, protecting both the IC and the battery during fault conditions like a shorted output or excessive ambient temperature.","metaTitle":"BQ24020DRCR Texas Instruments Li-Ion Battery Charger IC","metaDescription":"BQ24020DRCR from TI bqTINY™-II series: single-cell Li-Ion/Polymer charger, 500 mA max, USB interface, -40 to 125°C, 10-VSON.
