Note 1: Voltage may drop to 0 if backup supply is connected to Power Control pin. Negative voltage will cause a
large surge current. Protection fuse needed if battery polarity inversion is possible
Note 2: Maximum regeneration voltage in normal operation. Never inject a DC voltage from a battery or other fixed
source
Note 3: Minimum voltage must be present on VBat or Power Control wire
Note 4: Factory default value. Adjustable in 0.1V increments
Note 5: Current consumption is lower when higher voltage is applied to the controller’s VBat or PwrC-
trl wires Note 6: Estimate. Limited by heatsink temperature. Current may be higher with better cooling
Note 7: Factory default value. Adjustable in 0.1A increments
Note 8: Factory default value. Time in ms for power to go from 0 to 100%
