TB67S285FTG  
Toshiba BiCD process integrated circuit silicon monolithic  
TB67S285FTG  
Active Gain Control Serial Control Bipolar stepping motor driver  
The TB67S285FTG is a 3-wire serial controlled bipolar stepping  
motor driver with a built-in Active Gain Control architecture.  
The TB67S285FTG 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 TB67S285FTG is rated at 50 V, 3.0 A.  
P-VQFN48-0707-0.50-004  
Weight: 0.14 g (typ.)  
Features  
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=0.4 Ω (typ.))  
Built-in serial-parallel convert circuit  
Serial output function for cascade connection  
4 bit (16 steps) adjustable torque function  
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 TB67S285FTG.
