Toshiba BiCD Process Integrated Circuit Silicon Monolithic TB67S521FTAG TB67S521FTAG BiCD constant current two-phase bipolar stepping motor driver IC The TB67S521FTAG is a PWM chopper type 2-phase bipolar stepping motor driver IC. By applying the BiCD process, the TB67S521FTAG is rated at 40 V /2.8 A (Absolute maximum ratings). The on-chip VCC regulator allows control of a stepping motor with a single VM power supply. Features P-WQFN36-0606-0.50-002 Weght: 0.14 g (typ.) ● Bipolar stepping motor driver ● PWM constant current drive, PHASE-IN control ● Operational in full, half, and quarter step resolutions ● BiCD process: Use DMOSFET for the output power transistor. ● High withstand voltage and large current: 40 V / 2.
