The clock in decoder is built in. Fabricated with the BiCD process, rating is 50 V/4.0 A . FTG Features ・BiCD process integrated monolithic IC. ・Capable of controlling 1 bipolar stepping motor. ・PWM controlled constant-current drive. ・Allows full, half, quarter, 1/8, 1/16, 1/32 step operation. ・Low on-resistance (High + Low side=0.49Ω(typ.)) MOSFET 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 ・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. ・Chopping frequency of a motor can be customized by external resistance and capacitor. ・Multi package lineup TB67S109AFTG: P-WQFN48-0707-0.50-003 TB67S109AFNG: HTSSOP48-P-300-0.50 P-WQFN48-0707-0.50-003 Weight 0.10g (typ.)
