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
z Single-chip stepping motor controller/driver
z All inputs are TTL level.
z The CK1, CK2, CW/CCW and RESET pins are Schmitt
trigger inputs.
z Rotation direction control (Clockwise (CW)/counterclockwise
(CCW)): Single-clock and dual-clock modes
Weight : 1.11 g (typ.)
z Output enable and initial state detection capabilities
z High output withstand voltage: V_{CE (SUS)}φ = 28 V (MIN)
z High output current: I_OUTφ = 400 mA (MAX)
z Package: DIP-16
z The overvoltage protection circuitry is provided on each output. (It is activated when the output voltage
reaches 30 V (typ.) or higher.)
