TB67S213FTAG
TOSHIBA BiCD Integrated Circuit Silicon Monolithic
TB67S213FTAG
PWM method PHASE-IN Bipolar stepping motor driver
The TB67S213FTAG is a pwm method phase signal controlled
motor driver for two-phase bipolar stepping motor.
Using the BiCD process, the TB67S213FTAG is rated at
40V/2.5A.(Absolute maximum ratings)
Also, with the built-in VCC regulator, the TB67S213FTAG
can be operated with a single motor power(VM) supply.
FTAG
P-WQFN36-0606-0.50-002
Weight:0.14(g)
Features
・The
TB67S213FTAG can operate a single bipolar stepping motor.
・PWM
method current feedback control.
・Operational
in Full, Half, and Quarter step resolutions.
・Uses
low on-resistance MOSFETs for output stage.
・High
voltage and large current. (For specification, please refer to the absolute maximum ratings
and operation ranges.)
・Error
detection circuits (Thermal Shutdown(TSD), Over current shutdown(ISD), and Power-on reset(POR))
・The
built-in VCC regulator allows the TB67S213FTAG to operate with a single VM power supply.
・Customizable
PWM chopping frequency using the external components (resistance/condenser).
・Package:
TB67S213FTAG: P-WQFN36-0606-0.50-002
Note) Please be careful about thermal conditions during use.

* Please note that in the block diagram, functional blocks or constants may be omitted or simplified for explanatory purposes.
* Please make sure that all GND pins are shorted to the board’s ground pattern with a single point. Also, make sure to take extra
care with pattern layout, due to heat generation.
Please take extra care while tracing the layout of the VM, GND and output patterns to avoid shortage across output, GND
or power supplies. If such shortage occurs, the TB67S213 may be permanently damaged.
The utmost care should also be taken for pattern designing and implementation of the TB67S213. If power-relevant pins such as
VM, RS, OUT, and GND (which is capable of running particularly large current) are wired incorrectly, an operation error may occur
or the TB67S213 may be destroyed. The logic input pins must also be wired correctly. Otherwise, the TB67S213 may be damaged
by a current larger than the specified current running through the IC.
