Overview

Toshiba BiCD process integrated circuit silicon monolithic TB67S279FTG TB67S279FTG Active Gain Control Clock-in control Bipolar stepping motor driver The TB67S279FTG is a clock-in controlled bipolar stepping motor driver with a built-in Active Gain Control architecture.
The TB67S279FTG also has an internal current feedback control (ACDS) which enables the driver to control the motor current without using a sense resistor.
Using the BiCD process, the TB67S279FTG is rated at 50 V, 2.
0 A.
P-VQFN48-0707-0.
50-004 Features Weight 0.
14 g (typ.
) • Built-in Anti-stall architecture (AGC: Active Gain Control) • Built-in sense resistor less current control architecture (ACDS: Advanced Current Detection System) • Low Rds (on) MOSFET (High side+ Low side=0.
6 Ω (typ.
)) • Built-in micro stepping control.
(Full, Half (a), Half (b), Quarter, 1/8, 1/16, 1/32 step resolution) • Multi error detect functions (Thermal shutdown (TSD), Over current detection (ISD), Power-on-reset (POR), Motor load open (OPD)) • Error detection status output (Error Output) • Internal VCC (5 V) regulator enables the driver to operate with a single power supply (VM).
• Adjustable constant current PWM frequency using external components • Small package with thermal pad on back side (QFN48: 7.
0 mm x 7.
0 mm) Note: Please consider the heat condition when using the TB67S279FTG.
