Product Details

Demonstration circuits 1645A-A, 1645A-B, 1645A-C and 1645A-D feature the LTM8061, a 32V, 2A μModule^® Li-Ion battery charger. Operating from a 6.5V to 32V input source, the 1645A-A and 1645A-B demo circuits charge single cell Li-Ion batteries to float voltages of 4.1V or 4.2V respectively. The 1645A-C and 1645A-D demo circuits operate from a 12V to 32V input source, and charge dual cell Li-Ion battery packs to float voltages of 8.2V or 8.4V. JP1 turns the converter on or off. JP2 allows for easy selection of C/10 or timer charge termination.
