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). ・Low on-resistance (High + Low side=0.6Ω(typ.)) MOSFET output stage. ・High voltage and current (for specification, please refer to the absolute maximum ratings and operation ranges). ・Built-in error detection circuits (Thermal shutdown (TSD), over current shutdown (ISD), and power on reset(POR)). ・Built-in VCC regulator for internal use. ・Chopping frequency of a motor can be customized by external resistance and condenser. ・Package type: P-WQFN48-0707-0.50-003 Note) Please be careful about thermal conditions during use. ©2014 TOSHIBA CORPORATION 1 2014-10-20 Pin assignment (Top View) TB67S105FTG NC L_OUT VCC NC VM NC RS_B RS_B NC OUT_B+ OUT_B+ NC 36 35 34 33 32 31 30 29 28 27 26 25 NC C_OUT D_OUT 37 38 39 24 NC 23 NC 22 GND GND VREF_B VREF_A OSCM 40 41 42 43 TB67S105FTG 21 OUT_B20 OUT_B19 GND 18 GND NC 44 SI 45 SCK 46 RCK 47 NC 48 17 OUT_A16 OUT_A15 GND 14 NC 13 NC 1 2 3 4 5 6 7 8 9 10 11 12 NC SCLR- GSTANDBY GND NC RS_A RS_A NC OUT_A+ OUT_A+ NC Please mount the four corner pins of the QFN package and the exposed pad to the GND area of the PCB. 2 2014-10-20 Block diagram TB67S105FTG SCK RCK SI GSCLR- STANDBY 8bit shift register (Serial-Parallel Interface ) Main Control Logic Oscillator (Motor) Internal oscillator TSD ISD POR C_OUT L_OUT D_OUT OSCM GND VREF_A VREF_B Torque control VREF Comp A Bridge A NF level set VREF Comp B Bridge A NF level set VCC_REG RS CompA Bridge A Predriver Motor output stage Bridge A RS CompB Bridge B Predriver Motor output stage Bridge B VCC VM RS_A OUT_A+ OUT_A- RS_B OUT_B+ OUT_B- Functional blocks/circuits/constants in the block diagram may be omitted or simplified for explanatory purposes. 3 2014-10-20 TB67S105FTG Application Notes All the grounding wires of the TB67S105 must run on the solder mask on the PCB, and be externally connected at a single point. Also, the grounding method should be considered for efficient heat dissipation. Careful attention should be paid to the layout of the output, VM and GND traces, to avoid short circuits across output pins or to the power supply or ground. If such a short circuit occurs, the device may be permanently damaged. Also, the utmost care should be taken for pattern designing and implementation of the device since it has power supply pins (VM, RS, OUT, GND) through which a particularly large current may run. If these pins are wired incorrectly, an operation error may occur or the device may be destroyed. The logic input pins must also be wired correctly. Otherwise, the device may be damaged owing to a current running through the IC that is larger than the specified current. 4 2014-10-20 Pin explanations TB67S105FTG (QFN48) Pin No.1 to 28 Pin No. Pin Name Function 1 NC Non-connection pin 2 SCLR- Serial register clear pin (low active) 3 G- Serial data select pin (low active) 4 STANDBY Standby pin 5 GND Ground pin 6 NC Non-connection pin 7 RS_A Motor Ach current sense pin 8 RS_A Motor Ach current sense pin 9 NC Non-connection pin 10 OUT_A+ Motor Ach (+) pin 11 OUT_A+ Motor Ach (+) pin 12 NC Non-connection pin 13 NC Non-connection pin 14 NC Non-connection pin 15 GND Ground pin 16 OUT_A- Motor Ach (-) pin 17 OUT_A- Motor Ach (-) pin 18 GND Ground pin 19 GND Ground pin 20 OUT_B- Motor Bch (-) pin 21 OUT_B- Motor Bch (-) pin 22 GND Ground pin 23 NC Non-connection pin 24 NC Non-connection pin 25 NC Non-connection pin 26 OUT_B+ Motor Bch (+) pin 27 OUT_B+ Motor Bch (+) pin 28 NC Non-connection pin TB67S105FTG 5 2014-10-20 Pin No.29 to 48 Pin No. Pin Name Function 29 RS_B Motor Bch current sense pin 30 RS_B Motor Bch current sense pin 31 NC Non-connection pin 32 VM Motor power supply pin 33 NC Non-connection pin 34 VCC Internal VCC regulator monitor pin 35 L_OUT Serial ‘Latch’ output pin 36 NC Non-connection pin 37 NC Non-connection pin 38 C_OUT Serial ‘Clock’ output pin 39 D_OUT Shift register data output pin 40 GND Ground pin 41 VREF_B Motor Bch output current set pin 42 VREF_A Motor Ach output current set pin 43 OSCM Oscillating circuit frequency for PWM chopping set pin 4.
