Notes
All the grounding wires of the TB62262FTAG must run on the solder mask on the PCB and be externally
terminated at only one point. Also, a grounding method should be considered for efficient heat dissipation.
Careful attention should be paid to the layout of the output, VM and GND traces, to avoid short circuits across
output pins or to the power supply or ground. If such a short circuit occurs, the device may be permanently
damaged.
Also, the utmost care should be taken for pattern designing and implementation of the device since it has power
supply pins (VM, RS, OUT, GND) through which a particularly large current may run. If these pins are wired
incorrectly, an operation error may occur or the device may be destroyed.
The logic input pins must also be wired correctly. Otherwise, the device may be damaged owing to a current
running through the IC that is larger than the specified current.

Function explanation (Stepping motor)
1. CLK Function
Each up-edge of the CLK signal will shift the motor’s electrical angle per step.
TB62262FTAG
CLK Input
Up-edge
Down-edge
Function
Shifts the electrical angle per step.
(State of the electrical angle does not change.)
2. ENABLE function
The ENABLE pin controls the ON and OFF of the corresponding output stage. This pin serves to select if the motor
is stopped in Off (High impedance) mode or activated. Please set the ENABLE pin to ‘L’ during VM power-on and
power-off sequence.
ENABLE Input
H
L
Output stage=‘ON’ (Normal operation mode)
Output stage=’OFF’ (High impedance mode)
Function
3. CW/CCW function and the output pin function (Output logic at the time of a charge start)
The CW/CCW pin controls the rotation direction of the motor. When set to ‘Clockwise’, the current of OUTA is output
first, with a phase difference of 90°. When set to ‘Counter clockwise”, the current of OUTB is output first with a
phase difference of 90°.
CW/CCW Input
H : Clockwise operation(CW)
L : Counter clockwise operation(CCW)
4. Step resolution select function

Function
Standby mode (the OSCM is disabled and the output stage is
set to ‘OFF’ status)
Full step resolution
Half step resolution
Quarter step resolution
When switching the DMODE1,2; setting the RESET signal to Low (will set the electrical angle to the initial status),
is recommended.
