Using the LTC4000 high voltage, high performance controller designed by Linear Technology, can be designed a very simple high current LiFePO4 battery charger that will provide a fixed output voltage of 12 volts at a maximum output current of 15 A .
Also this electronic circuit project is designed for battery charging and power management .
Features of the LTC4000’s high current LiFePO4 battery charger include: accurate (±0.25%) programmable float voltage, selectable timer or current termination, temperature qualified charging using an NTC thermistor, automatic recharge, C/10 trickle charge for deeply discharged cells, bad battery detection and status indicator outputs.
LTC4000 battery charging and power management electronic circuit also includes precision current sensing that allows lower sense voltages for high current . This power supply circuit is very simple requiring few external electronic parts and is designed for charging three cell LiFePO4 battery pack , providing a maximum charge current of 10 ampere .
This charger circuit diagram electronic project supports a wide input voltage range , from 15 volt up to 60 volt .
