TP5100 Lipo Charger

Features / Specs

• Charger Chip: TP5100
• Input Voltage Range: 5 – 18VDC (Recommended Max is 12VDC)
• Constant Charge Current: 2A Default (Can be adjusted from 0.1A to 2A – Requires soldering)
• Trickle Charge Current: 10% of Constant Current = 200mA (No adjustment resistor on this board)
• Battery Compatibility: Lithium Ion / Lithium Polymer (Single Cell (4.2V) – 1S / Dual Cell (8.4V) – 2S)
• Charge Voltage: 4.2VDC / 8.4VDC
• Protection: Chip Over Temperature; Over-Current; Undervoltage; Short Circuit; Reverse battery
• Indication LEDs: Red LED indicates charging; Blue LED indicates charge complete; Both LEDs will be off when input voltage is disconnected
• “SET” jumper pads should be joined when charging a 2S (8.4V) battery
• Dimensions: ~(25mm x 17mm x 5.7mm)

• External LEDs can be connected if required. On-board LEDs should be removed first
• Charging LED can be connected between “CHRG” (Cathode) and “LED+” (Anode) pins
• Charge complete LED can be connected between “STDBY” (Cathode) and “LED+” (Anode) pins
