TB67S105FTG
Toshiba BiCD process integrated circuit silicon monolithic
TB67S105FTG
8bit Serial controlled bipolar stepping motor driver
The TB67S105FTG is a two phase bipolar stepping motor driver
using a PWM chopper, controlled by 8 bit serial.
Fabricated by the BiCD process, the TB67S105FTG is rated
at 50V/3.0A.
The internal voltage regulator allows to control the device
with a single VM power supply.
FTG
P-WQFN48-0707-0.50-003
Weight: 0.1 g (Typ.)
Features
・BiCD process integrated monolithic IC.
・Capable of controlling one bipolar stepping motor.
・PWM controlled constant-current drive.
・Built-in serial-parallel convert circuit (8bit shift register)
・3-line (Data, Clock, Latch) serial output function for cascade connection
・Allows full, half step operation
・4 bit (16 steps) adjustable torque function (TRQ1,TRQ2,TRQ3,TRQ4).

Note 1: Usually the maximum current value should be controlled below 70% or less of the absolute maximum ratings
for a standard based on thermal rating. The maximum output current may be further limited due to thermal
considerations, depending on ambient temperature and board conditions.
Note 2: Device alone. (Ta =25°C)
If the ambient temperature is above 25°C, the power dissipation must be de-rated by 10.4mW/°C.
Ta: Ambient temperature
Topr: Ambient temperature while the device is active
Tj: Junction temperature while the device is active. The maximum junction temperature is limited by the thermal
shutdown(TSD) circuitry. It is advisable to keep the maximum current below a certain level so that the maximum
junction temperature, Tj(max), will not exceed 120°C.
Caution) Absolute maximum ratings
The absolute maximum ratings of a semiconductor device are a set of ratings that must not be exceeded,
even for a moment. Do not exceed any of these ratings.
Exceeding the rating (s) may cause device breakdown, damage or deterioration, and may result in
injury by explosion or combustion.
The value of even one parameter of the absolute maximum ratings should not be exceeded under
any circumstances. The device does not have overvoltage detection circuit. Therefore, the device is
damaged if a voltage exceeding its rated maximum is applied.
All voltage ratings, including supply voltages, must always be followed. The other notes and
considerations described later should also be referred to.

conditions (exciting mode, operating time, etc), ambient temperature, and heat conditions (board condition and so
on).
