A Very High Efficiency 2S Direct Charger & Switched Capacitor with 13-bit ADC
The SM5441 is a high efficient two-cell direct charger for 2-cell. The two-cell direct charger is optimized for fast direct charging applications with peak efficiency up to 99% and the switched-capacitor converter delivers max 7A output current. The serial I 2 C interface provides full programmable options for secure and robust charging profile along with the battery protection schemes.
The embedded 13-bit ADC can measure many points such as VBUS input voltage/current, VBAT1/2 output voltage, IBAT1/2 current, VOUT output voltage, battery temperature via THEM voltage and the die temperature.
