Sensor resistor
The R
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
, can be
calculated by using the formula:
i
m
= (V
R
0.080) / R
S
[A], at 100% level
External recirculation diodes
Recirculation diodes must be connected
across each motor terminal and the
supply voltage, V
. The anodes shall be
connected to the motor terminals and
the cathodes to the V
voltage. Ultra-
fast recovery diodes should be used for
maximum performance and reliability.
