TB67S128HG CLOCK-in controlled Bipolar Stepping Motor Driver 1. Outline The TB67S128HG is a PWM controlled two-phase bipolar stepping motor driver with an integrated clock-in decoder. Fabricated with the BiCD process, the output rating is 50V/5.0A (Motor supply voltage = 44 V). 2. Features BiCD process integrated monolithic IC Capable of controlling 1 bipolar stepping motor. PWM controlled constant-current drive Low on-resistance (High + Low side = 0.25 Ω (typ.)) MOSFET output stage Weight: 7.6 g (typ.) Allows 1/1, 1/2, 1/4, 1/8, 1/16, 1/32, 1/64, and 1/128 step operation. Constant current PWM control (Mixed Decay) Integrated current sensing (ACDS: Advanced Current Detection System) High voltage and current (for specification, please refer to absolute maximum ratings and operating ranges) Multiple error detections (Thermal shutdown (TSD), Over current (ISD), and Power-on-reset (POR)). Built-in VCC regulator for internal circuit Adjustable PWM chopping frequency with external resistance and capacitor. TB67S128HG: HZIP25-P-1.00F package Note: Please be careful about thermal conditions during using.
