4.1 AAA Battery Holders
The battery pack includes 14 AAA battery holders connected in series. Each battery holder connects to the 34-pin connector and emulates
the voltage cells that connect to the MC3377x cell terminals in a real application.
The battery pack accepts any battery lower than 4.4 V that is compatible with the AAA format. For example:
• AAA 1.2 V NiMh batteries
• AAA 1.5 V Alkaline batteries
• 10440 3.7 V Lithium-ion batteries (flat top is preferred)
The bottom silkscreen of the PCB indicates the cell number for each battery holder.
A configuration jumper J4 allows you to route CT6 either to the next battery holder (MC33771 configuration), or to VBAT (MC33772
configuration). Place a jumper connection on J4 for the pack to be functional.
4.2 34-pin Cells Connector
The fourteen cells connect to the EVB through 34-pin header [X1-1...X1-34]:
