Functional description
2.1
Reference voltage
The voltage applied to VREF pin is the reference for the internal DAC and, together with the
sense resistor value, defines the maximum current into the motor winding according to the
following relation:
IMAX
=
-0---,--5----------V----R----E----F-
RS
=
--1---
FI
V-----R----E---F-
RS
where Rs = sense resistor value
