TB67S128FTG

TOSHIBA BiCD Integrated Circuit Silicon Monolithic

TB67S128FTG

CLOCK-in and Serial controlled Bipolar Stepping Motor Driver

1. Outline

The TB67S128FTG is a two-phase bipolar stepping motor driver using a

PWM chopper. The clock in decoder is built in.

Fabricated with the BiCD process, output rating is 50 V/5.0 A (Motor

supply voltage = 44 V).

2. Features



BiCD process integrated monolithic IC.

Capable of controlling 1 bipolar stepping motor.

Weight: 0.229 g (typ.)

PWM controlled constant-current drive

Low on-resistance (High + Low side = 0.25 Ω (typ.))

MOSFET output stage.

Allows full, half, quarter, 1/8, 1/16, 1/32, 1/64, 1/128 step operation.

High efficiency motor current control mechanism (ADMD: Advanced Dynamic Mixed Decay)

Built-in Anti-stall architecture (AGC: Active Gain Control)

Built-in Sense resistor less current control architecture (ACDS: Advanced Current Detection System)

High voltage and current (For specification, please refer to absolute maximum ratings and operation ranges)

Multi error detect functions (Thermal shutdown (TSD), Over current (ISD), Power-on-reset (POR), motor load open

(OPD)).

Error detection (TSD/ISD/OPD) flag output function

Built-in VCC regulator for internal circuit

Chopping frequency of a motor can be adjusted by external resistance and capacitor.

Small package with thermal pad

TB67S128FTG: P-VQFN64-0909-0.50-006

P-VQFN64-0909-0.50-006

Note: Please be careful about thermal conditions during using.
