TB67S539SFTG

BiCD Constant-Current Two-Phase Bipolar Stepping Motor Driver IC

The TB67S539SFTG is a two-phase bipolar stepping motor driver using a PWM

chopper.

Fabricated with the BiCD process, the TB67S539SFTG is rated at 40V/2.0A (Absolute

maximum ratings).

A stepping motor can be operated with a single VM power supply by built-in regulator.

Features

P-VQFN32-0505-0.50-004

Weight: 0.066 g (typ.)

 BiCD process monolithic IC.

 Capable of controlling bipolar stepping motor.

 Advanced Current Detect System (ACDS) realizes a PWM constant-current control without external current detection

resistors.

 Advanced Dynamic Mixed Decay (ADMD) realizes a high efficiency PWM constant-current control.

 Clock input control.

 Operational in full, half, quarter, 1/8, 1/16, and 1/32 step resolutions.

 BiCD process: Use DMOSFET for the output power transistor.

 High withstand voltage and large current drive: 40 V / 2.0 A (Absolute maximum ratings).

 Built-in thermal shutdown (TSD), over-current detection (ISD), and under voltage lockout (UVLO).

 External components for a charge pump are reduced.

 Package: QFN32 (5 mm × 5 mm).
