TB67S522FTAG,EL Toshiba

TB67S522FTAG Toshiba BiCD Process Integrated Circuit Silicon Monolithic TB67S522FTAG PWM method CLK-IN bipolar stepping motor driver The TB67S522FTAG is a PWM chopper type -twphoase bipolar stepping motor driver. By applying the BiCD process, the TB67S522FTAG is rated at 40 V/2.8 A . The internal voltage regulator allows control of the motor with a single VM power supply. P-WQFN36-0606-0.50-002 Weght: 0.14 g (typ.) Features Bipolar stepping motor driver PWM constant current drive Operational in full, half, and quarter step resolutions Low on-resistance of output stage transistor by using BiCD process High withstand voltage and large current (For details, refer to absolute maximum ratings and operating ranges.) Built-in thermal shutdown circuit (TSD), over-current detection circuit (ISD), and POR for VM power supply Built-in VCC regulator allows the TB67S522FTAG to function with only VM power supply. Able to customize PWM signal frequency by external resistance/capacitor. Package: P-WQFN36-0606-0.50-002 Note: Please be careful about thermal conditions during use. 1 2016 TOSHIBA Corporation 2016-12-13 TB67S522FTAG Pin Assignment (Top View) 27 26 25 23 22 20 19 24 21 GND NC 18 28 17 29 OUT B1- GND VREF B 30 16 OUT B2- 15 GND VREF A 31 TB67S522FTAG 14 NC OSCM 32 13 GND CW/CCW 33 MO OUT 34 12 OUT A2- 11 OUT A1- D MODE1 35 10 D MODE2 36 GND 1 3 4 6 7 9 2 5 8 *: Please mount the four corner pads of the package and the exposed pad to the GND area of the PCB. 2 2016-12-13 CLK IN NC ENABLE NC RESET VCC GND NC NC VM RS A1 RS B1 RS A2 RS B2 OUT A1+ OUT B1+ OUT B2+ OUT A2+
