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 Al.

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: VCE (SUS)φ = 28 V (MIN) z High output current: IOUTφ = 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.)

Excitation Mode Select Input 3-Phase/4-Phase Select Input See Truth Table B. Initial State Detection Output;this pin is set Low in the initial state. φ 1 Output φ 2 Output Ground φ 3 Output φ 4 Output Outputs φ 1 through φ 4 are enabled when this pin is High. Clock Output Clock Input 1 Clock Input 2 See Truth Table A. Reset Input; outputs are reset when this pin is Low (Note 1) VCC TRUTH TABLE A CK1 CK2 CW/CCW FUNCTION HL CW L L Inhibit (Note 2) H L CCW L L Inhibit (Note 2) HH CCW L H Inhibit (Note 2) H H CW L H Inhibit (Note 2) TRUTH TABLE B EA EB 3/4 (Note 3) LL L HL L LH L HH L LL H HL H LH H HH H FUNCTION 4-Phase Output 1-Phase Excitation 2-Phase Excitation 1−2-Phase Excitation Test Mode: All outputs are enabled 3–Phase Output 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, EA and/or EB 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. 2 2012-11-01 EQUIVALENT CIRCUITS EA, EB, 3/4, E VCccC IN 100kΩ 10kΩ GND 1.15V CK1, CK2, CW/CCW, R VVCcCc IN GND 100kΩ 10kΩ :1.15V :1V TB66.
