5V 2A Type-C Input Charge and Discharge Integrated Module

Integrated 5V2A high-precision charge-discharge module with Type-C input compatible with 4.2V lithium battery.

Principle of operation:

• The module output is switched off if the charge current is still below 50 mA.
• Supports external push buttons. Connect the push button to the K-point and the output pole. A short press turns on the power indicator and the 5 V output. Two consecutive short presses turn off the power indicator and the 5V output.
• The charging cycle is automatically interrupted when the charging current drops to 100 mA after reaching the final voltage.
• The charge cycle resumes when the battery voltage drops below 4.1V.
• If the battery voltage falls below 2.8 V, the battery is pre-charged with 180 mA.
• Supports simultaneous charging and discharging.
