Charger module

PDCharger Family description
The PDCharger is a smart charger module which manages the LiFePo4 battery charging with
extended functions and I2C control/monitoring for Charger chip, Gauge chip, and Microcontroller
onboard.
The Charger supports the narrow VDC power path management, in which the system is regulated at a voltage slightly higher than the battery voltage without being allowed to drop below the minimum system voltage. The minimum system voltage allows the system to operate even when the battery is completely discharged or removed. When system
power exceeds the input source rating, battery supplement mode supports the system power requirement without overloading the input source.
The device charges a battery from a wide range of input sources including external DC adapter and Solar Panels to high voltage PD adapter and traditional barrel adapter. The charger automatically sets converter to be a buck, boost, or buck-boost configurations based on input voltage and battery voltage without the host control. The dual input source selector manages the power flowing from two different input sources.
The inputs selection is controlled by the host through I2C with default source #1 (VAC1) as the primary input and the source #2 (VAC2) as the secondary input. USB PD connector is not assembled for the versions higher than V.2.0.

PDCharger module based on the newest STM32 microcontroller utilizing the power and cost effectiveness of the latest industry standards.

There are several PDCharger variants available :
PDCharger v.2.1 up to 12V @ 4A load
PDCharger v.2.2 up to 12V @ 10A+ load, additional mounting holes
for an optional heatsink, optimized for LiFePo4 batteries
