Scale Factor SLEW_CNTL to Curr. Reg. = 1/50
Scale Factor SLEW_CNTL to Curr. Reg. = 1/20
Scale Factor SLEW_CNTL to Curr. Reg. = 1/10
Use SLEW_CNTL for Current Regulation Voltage =
Curr. Reg. Voltage is fixed by registers R09 and R0A
Use SLEW_CNTL for Current Regulation Voltage =
Curr. Reg. Voltage = SLEW CNTL*scale factor D[7:6]
Use SLEW_CNTL for FET GATE Current Ramp =
FET GATE current is fixed at Max Current
Use SLEW_CNTL for FET GATE Current Ramp =
FET GATE current = (Max Current)*(SLEW CNTL)/2.5
Max FET GATE Current = (8+(n X 8))
