Toshiba TB67S549FTG Bipolar Stepping Motor Driver IC

Toshiba TB67S549FTG Bipolar Stepping Motor Driver IC is a PWM chopper type 2-phase bipolar stepping motor drive. The TB67S549FTG utilizes the BiCD process producing an output withstand voltage of 40V and a maximum output current of 1.5A. The Toshiba TB67S549FTG Bipolar Stepping Motor Driver IC offers flexibility by allowing operation via a single VM power supply with a built-in regulator.

Features

  • Monolithic device using BiCD process
  • Device for driving a bipolar stepping motor
  • A PWM constant current drive is realized without external current detection resistors owing to the built-in function of Advanced Current
  • Detect System (ACDS)
  • A high-efficiency PWM constant-current drive is realized owing to the built-in function of Advanced Dynamic Mixed Decay (ADMD)
  • Clock input control
  • Full, half, quarter, 1/8, 1/16, and 1/32 step resolutions are available
  • BiCD process: DMOSFETs are integrated for output power transistors
  • High withstand voltage and high output current: 40V / 1.5A (absolute maximum rating)
  • Over-temperature detection (TSD), over-current detection (ISD), and low supply voltage detection (UVLO) are built-in
  • Reduced external components for the charge pump
  • QFN24 (4mm x 4mm) Package
