8. PMBus Communication Interface
RPB-1600 is compliant with PMBus Rev.1.1, the maximum communication speed is 100KHz and it
has the capability of identifying up to 8 addressed units.

◎
Each RPB-1600 unit should have their unique and own device address to communicate over the
PMbus. This 7-bit address is defined as follows:
1
MSB
0 0 0 A2 A1 A0
LSB
A0-A2 allow users to designate the address for each RPB-1600 unit; these three bits are defined
through PIN7 (A0), PIN8 (A1) and PIN9 (A2) on CN1. There are up to 8 different addresses are
available to be assigned. When connecting one of these pins, for example, PIN8, with PIN14
(-V(Signal)), the corresponding bit, A1, is set to logic “0”; when it is kept open, for example, PIN7, the
corresponding bit, A0, is set to logic “1”. Please refer to Figure 8-1(left) for the detailed setup advice.
◎
The charging operation can be determined by the setup over D0, PIN10 on CN1. When D0 is logic
“0”, connecting PIN10 with PIN14(-V(Signal)), RPB-1600 follows a built charging curve to charge the
batteries; when D0 is logic “1”, PIN10 kept open, the charging operation is completely defined by the
control over PMBus, PV/PC or SVR. Please refer to Figure 8-2(right).
