Page 5: Understanding The Battery Pack
Understanding the Battery Pack BATT-14AAAPACK Overview The BATT-14AAAPACK is a 3-cell to 14-cell configurable battery pack designed to work in conjunction with evaluation boards such as the KIT33771TPLEVB, the KIT33771SPIEVB, or the KIT33772ASP1EVB. It offers a compact and easily accessible standard battery platform that connects directly to the evaluation boards through a 34-pin ribbon cable. -

Current Sense 14 x AAA Battery Holders Jumper (J7) Protection 6-cell /14-cell Fuse (F1) Selection Jumper (J4) Figure 3. Top View... - Page 7 Getting to Know the Hardware 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.
- Page 8 1.3mm Serial Charging Jack The BATT-14AAAPACK includes 1.3mm jack on the front of the pack to support external charging of the battery stack. However, the battery pack contains no internal charging circuitry. The pack also contains no overcurrent protection other than the F1 fuse. Therefore, be sure to select the proper smart charger when serial charging the batteries.

Page 9: Configuring The Hardware
Configuring the Hardware Basic Configurations The BATT-14AAAPACK is configured by default for an MC33771 and LOAD current sense. To use the battery pack with the MC33772, position the jumper J4 between pins 1 and 2. This routes CT6 directly to VBAT. - Page 10 Configuring the Hardware Cell Configuration The battery pack allows you to configure from three to six cells when used with the MC33772 and from seven to fourteen cells when used with the MC33771. The exact number of required cells depends on the device version. You may need to place AAA dummy batteries in some of the battery holders to match the requirements of your device.
