【ART-Pi】Lithium battery powered expansion board +717522A

This solution uses the SW6106 highly integrated two-way fast charging chip, which supports multiple fast charging protocols such as PD/QC/FCP/PE/SFCP, coulomb power, lighting driver and corresponding control management logic. Communicates with ART-Pi through I2C to provide accurate and safe power support for ART-Pi.

Features

Fast charging function

Type-C supports PD3.0/PD2.0/QC3.0/QC2.0/FCP/PE2.0/PE1.1/SFCP fast charge output and supports PD3.0/PD2.0 fast charge input. Battery 4.2V lithium battery

Coulomb power function

ART-Pi communicates with SW6106 through the I2C protocol to obtain the precise power information of the lithium battery and issue control instructions.

Protective function

When the chip temperature exceeds 115°C, the charging current begins to decrease. If the overtemperature continues to exceed 150°C, the chip enters over-temperature shutdown mode.

The charger supports NTC protection. The NTC temperature protection module will always monitor the battery temperature so that it can be charged within the normal temperature range of 0-50°C. When the temperature is abnormal, the charging current will be reduced or charging will be turned off. When the temperature is lower than 5°C, the charging current is reduced by half. If the temperature continues to drop below 0°C, charging is turned off. It will automatically recharge after the temperature rises to 5°C. The charging current is reduced by half. When the temperature continues to rise to 10°C, Restore normal charging current. When the temperature is higher than 45°C, the charging current is reduced by half. If the temperature continues to rise above 50°C, charging is turned off. It will automatically recharge after the temperature drops to 45°C. The charging current is reduced by half. When the temperature continues to drop to 40°C , restore normal charging current.
