Component List

  1. IC LT4060
  2. NTC Thermistor
  3. Resistors
  4. LED
  5. Transistor MJD210
  6. Capacitors


Circuit schematic like in figure 1 above is Ni-MH Battery Charger using LT4060. With a little modifying the circuit, In addition to Ni-MH batteries Ni-Cd batteries can be also charged. Connect the CHEM pin (pin12) of the IC to +Vcc to charge Ni-Cd batteries. Here the circuit is configured to charge 2 cells connected in series. Upto 4 batteries in series can be charged using this circuit by fixing the connections of SEL0 and SEL1 pins. Connect SEL0 and SEL1 pins to GND to charge a  single cell. Connect SEL1 to GND and SEL0 to Vcc to charge two cells. Connect SEL1 to VCC and SEL0 to GND to charge three cells. Connect SEL0 and SEL1 pins to VCC to  charge 4 cells. The circuit also features temperature based charge qualification. An NTC thermistor connected at the NTC pin (pin11) of the IC serves as the temperature sensor.
