TB67S142NG Toshiba BiCD Process Integrated Circuit Silicon Monolithic TB67S142NG Clock controlled Unipolar stepping motor driver NG The TB67S142NG is a Clock controlled PWM chopping type 2 phase unipolar stepping motor driver. Using the BiCD process, the TB67 S142NG 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 Weight 1.29(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 2014-05-20 TB67S142NG Pin assign (TB67S142NG) (Top View) VCC VM 1 24 VREF 2 23 GND OSCM VCOM 3 22 ERR 4 21 OUTB+ ALM RSGNDB 5 20 MO 6 19 OUTB- DMODE1 OUTA- 7 18 DMODE2 8 17 RSGNDA RESET 9 16 OUTA+ CLK NC 10 15 ENABLE 11 14 GND CW/CCW BRAKE 12 13 2 2014-05-20
