TB6615PG
TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC
TB6615PG
STEPPING MOTOR CONTROLLER / DRIVER
The TB6615PG is a stepping motor controller/driver with MOS output transistors.
The TB6615PG can drive a two-phase stepping motor in unipolar
mode, and allow the selection of rotation direction between
forward and reverse by using clock signals. It also supports
several excitation modes (1-phase, 2-phase and 1-2-phase).
FEATURES
Single-chip stepping motor controller/driver
All inputs are TTL level.
The CK1, CK2, CW/CCW and RESET pins are Schmitt
trigger inputs.
Rotation direction control (Clockwise (CW)/counterclockwise
(CCW)): Single-clock and dual-clock modes
Output enable and initial state detection capabilities
High output withstand voltage: V
CE (SUS)
φ
= 28 V (MIN)
High output current: I
OUT
φ
= 400 mA (MAX)
Package: DIP-16
The overvoltage protection circuitry is provided on each output. (It is activated when the output voltage
reaches 30 V (typ.) or higher.)
Weight : 1.11 g (typ.)

Test Mode: All outputs are enabled
1-Phase Excitation
2-Phase Excitation
1-2-Phase Excitation
Test Mode: All outputs are enabled.
Note 1: Setting the Reset pin Low causes the output state to enter the initial state, and the
MO
output to
become Low.
Once the Reset pin is set High, the output state enters the state following the initial state at the next
rising edge of the clock signal.
Note 2: Do not use Inhibit mode.
Note 3: Before switching the 3/4, E
A
and/or E
B
pins, put the TB6615PG into Reset mode by applying the
Reset pulse.
Note 4: A two-phase stepping motor should be driven in four-phase output modes.
