Toshiba Electronic Devices & Storage Corporation Adds New Three-Phase Brushless Fan Motor Controller IC Allowing Easy Switching to Multipolar Motor

TOKYO--(BUSINESS WIRE)--Sep. 29, 2017

Toshiba Electronic Devices & Storage Corporation (TDSC) today announced the launch of “TB67B054FTG,” a new three-phase brushless fan motor controller IC for home appliances, such as air conditioners and air purifiers, that realizes high efficiency drive and noise reduction. Mass production will start in November, 2017.

Today’s motor rotors are multi-polarized, since higher motor driving efficiency and noise reduction are required for fan motors used air conditioners, air purifiers and other in home appliances. Conventionally, motor control is carried out by a microcontroller and an 8-pole rotor and a rotation-control signal that outputs 3 pulses a cycle.

The new product can control the rotation speed of a 12-pole rotor with a standard microcontroller system by using a rotation-control signal that outputs 2 pulses in one cycle. Switching from an 8-pole to 12-pole rotor achieves higher drive efficiency and reduces noise, but rotation-control for an 8-pole rotor can also adopted, which shortens the development term.

The controller is housed in a small surface-mount 32-pin QFN type package, which has a 68% smaller mounting area than the widely used 30-pin SSOP type package, contributing to space- saving in the board layout.

Main Features

  1. Realizes low vibration and noise with a sine-wave PWM drive
  2. Possible to upgrade from 8-pole rotor to 12-pole rotor motor without changing the rotation-control system. Since the rotation-control signal outputs 2 pulses in one cycle, the current rotation-control system for an 8-pole rotor can be applied with a 12-pole rotor.
  3. Small surface-mounting type package

    Housed in a small, 32-pin QFN package (mounting area: 5×5mm). The mounting area is 68% smaller than for products in 30-pin SSOP type packages (mounting area: 32.8×13.5mm), contributing to space-saving in mounting and board layout.
