DESCRIPTION
The M54670P is a semiconductor IC to drive a bipolar stepper
motor directly by controlling the coil current with the constant
current method.
FEATURES
G
Wide operating voltage range (10 – 35V)
G
Wide output current control range (20 – 800mA)
G
Bipolar and constant current drive
G
Built in flywheel
G
Current level can be changed by steps or continuously.
G
Built in a thermal shutdown circuit
APPLICATION
Office automation equipment such as printer, FDD, HDD, and FAX
FUNCTION
The M54670P can drive a stepper motor by the 2-phase bipolar
method and also control the coil current. Furthermore, it controls
the direction of the coil current with Ph input pins (pins 3 and 30).
The coil current value can be selected among four levels (0 to
max.) by selecting the combination of three internal comparators by
logic input (pins 14, 15, 18 and 19). It also can be continuously
controlled with V
R
pins (pins 2 and 31). By selecting an I input pin
among pins 14, 15, 18 or 19, the operation timing, 2-phase
excitation, 1-2-phase excitation or microstep, can be selected.
Because two control circuits are built in this IC, a stepper motor can
be driven with a single IC by the 2-phase bipolar method.
