TB67S101AFG/FTG/FNG TOSHIBA BiCD Integrated Circuit Silicon Monolithic TB67S101AFG, TB67S101AFTG, TB67S101AFNG FG PHASE-in controlled Bipolar Stepping Motor Driver The TB67S101A is a two-phase bipolar stepping motor driver using a PWM chopper. An interface is PHASE in control. Fabricated with the BiCD process, rating is 50 V/4.0 A . HSOP28-P-0450-0.80 Features Weight 0.79g (Typ.) BiCD process integrated monolithic IC. Capable of controlling 1 bipolar stepping motor. PWM controlled constant-current drive. FTG Allows full, half, quarter step operation. Low on-resistance (High + Low side=0.49(typ)) MOSFET output stage. High efficiency motor current control mechanism (Advanced Dynamic Mixed Decay) High voltage and current (For specification, please refer to absolute P-WQFN48-0707-0.50-003 maximum ratings and operation ranges) Weight 0.10g (Typ.) Built-in error detection circuits (Thermal shutdown (TSD), over-current shutdown (ISD), and power-on reset (POR)) Built-in VCC regulator for internal circuit use. FNG Chopping frequency of a motor can be customized by external resistance and condenser.
