The output current setting reference voltage can be switched between four levels with the serial data.
This setting is useful for saving power in the motor powered hold state.
Calculating the Set Current
Since the reference voltage can be modified (0.2, 0.134, 0.1, and 0.66V) with the serial data, the output current can be
set with the reference voltage and the resistor RF connected between the RF pin and ground.
IOUT = (<reference voltage> × <set current ratio>)/<RF resistor value>
Example: If the reference voltage is 0.2 V, the set current ratio is 100%, and the RF resistor value is 1
, then the output
current will be that shown below.
IOUT = 0.2V × 100%/1 = 200mA
