Toshiba Launches High Resolution Micro-Stepping Motor Driver IC

Toshiba Electronic Devices & Storage Corporation has launched “TC78H670FTG,” the latest addition to its line-up of micro-stepping motor driver ICs.

ToshibaThe new IC has a maximum rating of 18V/2.0A and can drive motors with a wide range of operating voltages.

The new IC can drive a 128 micro-stepping motor with a power supply ranging from 2.5V to 16V. Its wide range of applications includes USB-powered, battery-powered, and standard 9-12V system devices, and it can also be used with a 1.8V interface, allowing connection to various hosts and microcontrollers.

Toshiba’s newest DMOS process ensures that TC78H670FTG realizes excellent figure-of-merit low ON resistance. The process also contributes to the IC’s ultra-low standby current. The IC is housed in a compact QFN16 package and eliminates use of a current sense resistor by incorporating a current detection part that contributes to lower cost, a smaller component footprint, and PCB routing space savings.

Features

  • Compact package (QFN16 3.0mm×3.0mm)
  • Low ON resistance (Ron=0.48Ω @VM=12V)
  • Low to medium voltage range 2.5V to 16V with interface of 1.8V to 5.0V
  • Ultra-low standby current of 0.1μA
  • Operates motors smoothly and quietly and reduces vibration; improved rotation angle accuracy[3] achieved by micro-stepping control.

Applications

  • Cameras, security cameras, portable printers, handheld scanners, pico-projectors, and smartphones
