TB67S521FTAG Toshiba BiCD Process Integrated Circuit Silicon Monolithic TB67S521FTAG BiCD constant current two-phase bipolar stepping motor driver IC The TB67S521FTAG is a PWM chopper type 2-phase bipolar stepping motor driver IC. By applying the BiCD process, the TB67S521FTAG is rated at 40 V /2.8 A (Absolute maximum ratings). The on-chip V regulator allows control of a stepping motor CC with a single V power supply. M P-WQFN36-0606-0.50-002 Weght: 0.14 g (typ.) Features Bipolar stepping motor driver PWM constant current drive, PHASE-IN control Operational in full, half, and quarter step resolutions BiCD process: Use DMOSFET for the output power transistor. High withstand voltage and large current: 40 V / 2.8 A (Absolute maximum ratings) Built-in thermal shutdown circuit (TSD), over-current detection circuit (ISD), and POR Package: P-WQFN36-0606-0.50-002 1 2016 TOSHIBA Corporation 2016-12-13 TB67S521FTAG Pin Assignment (Top View) 27 26 25 24 23 22 21 20 19 GND NC 18 28 17 GND 29 OUT B1- VREF B 30 16 OUT B2- VREF A 15 GND 31 TB67S521FTAG OSCM 14 NC 32 33 13 GND IN A1 IN A2 34 12 OUT A2- 11 OUT A1- PHASE A 35 10 PHASE B 36 GND 1 2 3 4 5 6 7 8 9 2 2016-12-13 IN B1 NC IN B2 NC STANDBY VCC GND NC NC VM RS A1 RS B1 RS A2 RS B2 OUT A1+ OUT B1+ OUT A2+ OUT B2+
