TB67S142FTG Toshiba BiCD Process Integrated Circuit Silicon Monolithic TB67S142FTG Clock controlled Unipolar stepping motor driver FTG The TB67S142FTG is a Clock controlled PWM chopping type 2 phase unipolar stepping motor driver. Using the BiCD process, the TB67 S142FTG 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 Features Weight 0.1(g) typ. BiCD processed monolithic integrated circuit. Capable of operating one unipolar stepping motor. PWM controlled constant current drive. Full, half(a), quarter 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 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. 1 2014-04-14 TB67S142FTG Pin assign (TB67S142FTG) (Top View) 34 33 32 31 30 29 28 27 36 35 26 25 OUTB+ 24 OSCM 37 OUTB+ 23 ERR 38 RSGNDB 22 ALM 39 RSGNDB 21 MO 40 20 OUTB- NC 41 19 OUTB- NC 42 TB67S142FTG 18 OUTA- NC 43 OUTA- 17 NC 44 16 RSGNDA NC 45 15 RSGNDA DMODE1 46 14 OUTA+ DMODE2 47 13 OUTA+ RESET 48 1 3 4 6 7 9 10 12 2 5 8 11 Please mount the four corner pins of the QFN package and the exposed pad to the GND area of the PCB. 2 2014-04-14 NC NC NC VREF CLK VCC NC VCC NC ENABLE CW/CCW VM NC BRAKE GND GND NC NC NC VCOM VCOM NC NC NC
