DESCRIPTION
Demonstration circuits 1645A-A, 1645A-B, 1645A-C and
1645A-D feature the LTM8061, a 32V, 2A μModule
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. JP1 turns the
