1 dc1645af DEMO MANUAL DC1645A-A/DC1645A-B/ DC1645A-C/DC1645A-D DESCRIPTION LTM8061-4.1/LTM8061-4.2/ LTM8061-8.2/LTM8061.4 32V, 2A µModule Li-Ion Battery Charger 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 fl oat 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 bat- tery packs to fl oat voltages of 8.2V or 8.4V.
