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.
