TB67S145FTG Toshiba BiCD Process Integrated Circuit Silicon Monolithic TB67S145FTG Serial controlled unipolar stepping motor driver FTG The TB67S145 is a serial controlled PWM chopping type, 2 phase unipolar stepping motor driver. Using the BiCD process, the TB67S 145 can be operated with VM voltage of 45V, output voltage of 84V, and output current of 3.0A at max (absolute maximum ratings). P-WQFN48-0707-0.50-003 Weight: 0.1 g (Typ.) Features BiCD process monolithic integrated circuit. Capable of operating one unipolar stepping motor PWM controlled constant current drive Full, half step resolution Low on resistance (0.25 (Typ.)) output MOSFET High voltage and current (for specification, please refer to the absolute maximum ratings and operation ranges). Brake mode function Standby (low power) mode function 4 bit-16 setting torque adjust function Serial to parallel convert circuit (8bit shift register) built in. Capable of 3 line logic (Data/Clock/Latch signal) output function (controllable by cascade connection) Error detect feedback signal output function (Over current/Thermal shutdown). Error detect function (Thermal shutdown(TSD), Over current(ISD), and Low voltage(POR). Built-in VCC regulator for internal circuit use. Fixed off time can be adjusted by external components. Note) Please be careful about the thermal conditions during use. 2014 TOSHIBA CORPORATION 1 2014-10-30 TB67S145FTG Pin assignment (TB67S145FTG) (Top View) 34 33 32 31 30 29 28 27 26 25 36 35 OUTB+ 24 OSCM 37 OUTB+ 23 ERR 38 RSGNDB 22 ALM 39 RSGNDB 21 NC 40 OUTB- 20 LOUT 41 19 OUTB- COUT 42 TB67S145FTG 18 OUTA- DOUT 43 OUTA- NC 17 44 16 RSGNDA DATA 45 15 RSGNDA CLOCK 46 14 OUTA+ LATCH 47 13 OUTA+ NC 48 1 2 3 4 5 6 7 8 9 10 11 12 (*) Please mount the four corner pins of the QFN package and the exposed pad to the GND area of the PCB. 2 2014-10-30 NC NC NC VREF CLR VCC NC VCC NC GATE STANDBY VM NC BRAKE GND GND NC NC NC VCOM VCOM NC NC NC
