TB62213AFNG
BiCD Integrated Circuit Silicon Monolithic
TB62213AFNG
PHASE-in controlled Bipolar Stepping Motor Driver IC
The TB62213AFNG is a two-phase bipolar stepping motor driver using
a PWM chopper. Fabricated with the BiCD process, the TB62213AFNG
is rated at 40 V/3.0 A . The on-chip voltage regulator allows control of
a stepping motor with a single VM power supply.

Capable of controlling 1 bipolar stepping motor.
BiCD process integrated monolithic IC.
PWM controlled constant-current drive.
Allows Full Step, Half Step and 1/4 Step excitations.
Output stage low on resistance by a BiCD process
High voltage and current (For specification, please refer to absolute maximum ratings and operating ranges)
Built-in error detection circuits
(Thermal shutdown (TSD),over-current shutdown (ISD), and power-on reset (POR))
Built-in VCC regulator for internal circuit use. Therefore it's possible to operate only by a VM power supply.
Chopping frequency of a motor can be customized by external resistance and capacitor.
High-speed Chopping by more than 100 kHz is possible.
Packages: HTSSOP48-P-300-0.50
Weight: 0.2g(Typ.)
Note) Please be careful about
thermal conditions during use.

Note
All the grounding wires of this product must run on the solder within the mask of the PCM. It must also be
externally terminated at a single point. Also, the 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 IC may be permanently
damaged.Also, the utmost care should be taken for pattern designing and implementation of the IC 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 this IC may be destroyed.
The logic input pins must be correctly wired, too. Otherwise, the IC may be damaged owing to a current running
through the IC that is larger than the specified current.
