TB67S109AFTG/FNG TOSHIBA BiCD Integrated Circuit Silicon Monolithic TB67S109AFTG, TB67S109AFNG CLOCK-in controlled Bipolar Stepping Motor Driver The TB67S109A is a two-phase bipolar stepping motor driver using a PWM chopper. The clock in decoder is built in. FTG Fabricated with the BiCD process, rating is 50 V/4.0 A . Features BiCD process integrated monolithic IC. Capable of controlling 1 bipolar stepping motor. P-WQFN48-0707-0.50-003 PWM controlled constant-current drive. Weight 0.10g (typ.) Allows full, half, quarter, 1/8, 1/16, 1/32 step operation. Low on-resistance (High + Low side=0.49 (typ.)) MOSFET FNG output stage. High efficiency motor current control mechanism (Advanced Dynamic Mixed Decay) High voltage and current (For specification, please refer to absolute maximum ratings and operation ranges) Error detection (TSD/ISD) signal output function HTSSOP48-P-300-0.50 Built-in error detection circuits (Thermal shutdown (TSD), over-current Weight 0.21g (typ.) shutdown (ISD), and power-on reset (POR)) Built-in VCC regulator for internal circuit use. Chopping frequency of a motor can be customized by external resistance and capacitor.
