TOSHIBA BiCD Integrated Circuit Silicon Monolithic
TB67S269FTG
CLOCK-in controlled Bipolar Stepping Motor Driver
The TB67S269 is a two-phase bipolar stepping motor driver
using a PWM chopper. The clock in decoder is built in.
Fabricated with the BiCD process, rating is 50 V/2.0 A .
FTG
Features
・BiCD process integrated monolithic IC.
・Capable of controlling 1 bipolar stepping motor.
・PWM controlled constant-current drive.
・Allows full, half, quarter, 1/8, 1/16, 1/32 step operation.
・Low on-resistance (High + Low side=0.8Ω(typ.)) MOSFET
output stage.
・High efficiency motor current control mechanism (Advanced
Dynamic Mixed Decay)
・High voltage and current (For specification, please refer to absolute

Application Notes
All the grounding wires of the TB67S269 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, VDD(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.
