NOTE: When operating in this mode, PMBus commands B0h/B1h…B8h can be set but there will
be no response whereas other PMBus commands and functions work normally.
PMBus, PV/PC or SVR Functions
Users are able to fully control and design the entire charging behavior, without the charging curve, by
one of the following means- PMBus command, PV/PC function or SVR adjustment. The operating
priority is, PMBus > PV/PC > SVR.

Charging Curve
When it is opted for charging curve, D0 set to 0, charging curve function is enabled with additional
PMBus commands. There are 4 built-in charging curves, “default” curve, one pre-defined curve for “gel
battery”, one pre-defined curve for “flooded battery” and one pre-defined curve for “AGM battery”.
Each curve can be selected by Command B4h CURVE_CONFIG.
In addition users are able to customize their own charge curves which will be stored to “default” after

NOTE: 1. The updated charging parameters is saved into EEPROM. The updated charging curve
takes effect after RPB-1600 is restarted.
2. When charging curve is enabled, the following commands will be invalid while other PMBus
commands are effective: Command 01h OPERATION (regarding Remote ON-OFF function),
Command 22h VOUT_TRIM (regarding Output voltage programming function) and
Command 46h IOUT_OC_FAULT_LIMIT (regarding Output current programming function).
