TB67S141NG Toshiba BiCD Process Integrated Circuit Silicon Monolithic TB67S141NG Phase controlled Unipolar stepping motor driver NG The TB67S141 is a Phase controlled PWM chopping type 2 phase unipolar stepping motor driver. Using the BiCD process, the TB67 S141 can be operated with VM voltage of 45V, output voltage of 84V, and output current of 3.0A at max (absolute maximum ratings). Features P-SDIP24-0723-1.78-001 BiCD processed monolithic integrated circuit. Weight 1.29(g) (typ.) 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. 2014 TOSHIBA CORPORATION 1 2014-10-10 TB67S141NG Pin assignment (Top View) VCC 1 24 VM VREF 2 23 GND OSCM 3 22 VCOM ERR 4 21 OUTB+ ALM 5 20 RSGNDB PHASEA 6 19 OUTB- PHASEB 7 18 OUTA- INA1 8 17 RSGNDA INA2 9 16 OUTA+ INB1 10 15 NC INB2 11 14 GND STBY 12 13 BRAKE 2014 TOSHIBA CORPORATION 2 2014-10-10
