4. Channel 5
Channel 5 is constant current driver. motor current is determined by ADJ3 voltage V
ADJ3
, sensing resistance R
SENSE
and GAIN3
input and calculated by the following equation.
when, GAIN3 = Low
when, GAIN3 = High
where, R
W
is internal bonding resistance and metal resistance is around 0.05
If oscillation or overshoot will be appeared in the output terminals, add external capacitors at FC1 and FC2 terminals. The output
response time depend on the FC1/FC2 capacitance and interval of input signal.
