11. Output current reference voltage
I2C communication allows the voltage to be switched to one of 16 steps from 0.200V to 0.050V. This is effective for
reducing power consumption when stepping motor holding current is supplied.
The output current is determined from the internal reference voltage and the resistance value connected between the
current-sense resistor connection pin (RF) and GND.
The formula used to calculate the output current is given below.
(Output constant current) = (Constant current reference voltage) ÷ (RF resistance value)
Example: With a 0.200V internal reference voltage, 1.0
Ω RF resistance and 100% current ratio
Iout = 0.2V
× 100% ÷ 1.0Ω = 200mA
Output current reference voltage values for 1/2 channels and 3/4 channels are set as shown below.
1/2 channels setting
Register address (A7 = “0”, A6 = “0”, A5 = “0”, A4 = “0”, A3 = “0”, A2 = “0”, A1 = “0”, A0 = “0”)
3/4 channels setting
Register address (A7 = “0”, A6 = “0”, A5 = “0”, A4 = “0”, A3 = “0”, A2 = “0”, A1 = “0”, A0 = “1”)
