3-phase motor driver for CD-ROMs

ROHM Semiconductor 

Motor driver ICs

(2) Torque command

The RNF pin voltage with respect to the torque command

(EC) is as follows:

BA6848FP / BA6853FS

The I / O gain GEC from EC pin to RNF pin (output current)

is determined by the RNF detector resistance.

GEC = 0.255 / RNF [A / V]

The torque limit current ITL is:

ITL = 0.35 / RNF [A]
