The 3S lithium battery pack charging module has an input voltage range of 6.6-30V. However, it is a step-down module after all, so it is recommended that the input voltage be greater than 14V.
The CN3763 DCDC chip used has trickle current, constant current and constant voltage charging modes, which is very suitable for lithium battery charging management. In constant voltage charging mode, CN3763 modulates the battery voltage at 12.6V, which can also be adjusted upward through an external resistor; in constant current charging mode, the charging current is set through an external resistor
Can fine-tune the output voltage
CN3763 is available in 10-pin SSOP package.
Simple peripherals, low cost, high efficiency
