Sensor resistor
The R
S resistor should be of a non-
inductive type power resistor. A 0.5 ohm
resistor, tolerance
≤ 1%, is a good
choice for 800 mA max motor current at
V
R = 5V.
The peak motor current, i
m , can be
calculated by using the formula:
i
m = (VR 0.080) / RS [A],
at 100% level
External recirculation diodes
Recirculation diodes must be connected
across each motor terminal and the
supply voltage, V
MM. The anodes shall be
connected to the motor terminals and
the cathodes to the V
MM voltage. Ultra-
fast recovery diodes should be used for
maximum performance and reliability.
