(1)

During short circuit condition driver current limit comparator will trip and short is detected and driver goes into STANDBY and short flag

is set high in the status register.

(2)

When testing VCM open or short this is the recommended minimum VCM code (in dec) to be used.

(3)

This is the voltage that is needed for the feedback resistor and high side driver. It should be noted that the maximum VCM resistance is

0.4 V)/102.3 mA = 25.4

Ω.
