BQ77216 EVM Getting Started Guide
2 BQ77216 EVM Getting Started Guide
2.1 Before You Begin
The following warnings and cautions are noted for the safety of anyone using or working close to the BQ77216
EVM. Observe all safety precautions.
2.2 Warnings and Cautions
!
The BQ77216 does not limit performance to the ratings of the EVM. Set equipment appropriately to
limit voltage and current for safe operation.
The circuit module has signal traces, components, and component leads on the bottom of the board.
This may result in exposed voltages, hot surfaces or sharp edges. Do not reach under the board
during operation.
The circuit module may be damaged by over temperature. To avoid damage, monitor the
temperature during evaluation and provide cooling, as needed, for your system environment. Do not
operate beyond the current and voltage limits in the Sepcification Table.
Some power supplies can be damaged by application of external voltages. If using more than 1
power supply, check your equipment requirements and use blocking diodes or other isolation
techniques, as needed, to prevent damage to your equipment.
Connections for rated current must be made at the terminal block. Test points are not rated for the
board current.
2.3 Quick Start
The BQ77216 is configured for cell count by the connections on the board. By default the board is set up for 16
cells and this quick start is for all 16 cells. When fewer cells are used, refer to
voltage appropriately.
These steps describe quick connection of the BQ77216 EVM to demonstrate operation of the protector function
the EVM. For more detailed descriptions, refer to other sections of the user guide.
Refer to
Figure 2-1
for the following steps.
1. Install the cell simulator shunts.

Warning
The BQ77216EVM is not rated as a high voltage EVM, has smaller clearances
than normally used on high voltage boards and does not have an isolation
boundary. If you apply high voltage to this board, all terminals should be
considered high voltage. Electric shock is possible when connecting the board to
live wire. The board should be handled with care by a professional. For safety, use
of isolated test equipment with overvoltage and overcurrent protection is highly
recommended.
Caution
Do not leave the EVM powered when unattended.
