TB67S249FTG
Active Gain Control Clock-in control Bipolar stepping motor driver
The TB67S249FTG is a clock-in controlled bipolar stepping
motor driver with a built-in Active Gain Control architecture.
The TB67S249FTG 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 TB67S249FTG is rated at 50 V,
4.5 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=0.33 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 protection (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 TB67S249FTG.
