T B 67S 508FTG TOSHIBA BiCD Integrated Circuit Silicon Monolithic TB67S508FTG BiCD Constant-Current Two-Phase Bipolar Stepping Motor Driver IC The TB67S508FTG is a two-phase bipolar stepping motor driver using a PWM chopper. Fabricated with the BiCD process, the TB67S508FTG rating is 40 V/3.0 A. Motor can be operated with single power supply (VM) by built-in regulator. P-VQFN36-0505-0.50-002 Weight: 0.06 g (Typ.) Features BiCD process monolithic IC Capable of controlling bipolar stepping motor PWM controlled constant-current drive without resistance for motor current detection Built-in ACDS (Advanced Current Detect System) function enables a PWM constant current control without external current detection resistors. Built-in ADMD(Advanced Dynamic Mixed Decay) function enables a high efficiency PWM constant current control. I/F: Capable of switching between the phase input control and the clock input control Full-step/Half-step/Quarter-step resolutions BiCD: DMOSFET is adopted to output power transistor. High withstand voltage and large current: 40 V / 3.0 A (absolute maximum ratings) Built-in thermal shutdown detection (TSD), Over current detection (ISD), and Under voltage lockout detection(UVLO) Decreasing number of external components by reducing charge pump Package: P-VQFN36-0505-0.50-002 1 2017 TOSHIBA Corporation 2017-03-01 T B 67S 508FTG Pin Assignment IFSEL=H (Phase input control) (Top View) 27 23 20 26 25 24 22 21 19 18 MGND OSCM 28 17 29 MGND VREF A VREF B 30 16 OUT B- OUT B- GND 31 15 TB67S508FTG NC IFSEL 14 32 13 OUT A- IN A1 33 IN A2 12 OUT A- 34 11 MGND IN B1 35 IN B2 36 10 MGND 3 6 9 1 2 4 5 7 8 IFSEL=L (Clock input control) (Top View) 27 23 20 26 25 24 22 21 19 18 MGND OSCM 28 17 29 MGND VREF A VREF B 30 16 OUT B- OUT B- GND 31 15 TB67S508FTG NC IFSEL 14 32 13 OUT A- CW/CCW 33 MO 12 OUT A- 34 11 MGND DMODE1 35 DMODE2 36 10 MGND 3 6 9 1 2 4 5 7 8 2 2017-03-01 CLK /STANDBY TEST1 TEST1 ENABLE PHASE A NC NC RESET PHASE B CC CC GND GND TEST2 TEST2 NC NC NC NC VM VM VM VM VM VM VM VM OUT A+ OUT A+ OUT B+ OUT B+ OUT B+ OUT B+ OUT A+ OUT A+
