TB6615PG,8 Toshiba

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 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 = 28 V (MIN) CE (SUS) z High output current: I = 400 mA (MAX) OUT 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.)

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 and/or E pins, put the TB6615PG into Reset mode by applying the A B Reset pulse. Note 4: A two-phase stepping motor should be driven in four-phase output modes. 2 2012-11-01
