Toshiba TB67B054FTG three-phase brushless fan motor controller IC

The TB67B054FTG is a new three-phase brushless fan motor controller IC for home appliances such as air conditioners and air purifiers that realizes high efficient drive and noise reduction.

When a motor is upgraded from existing 8-pole rotor to 12-pole rotor type, the new product can control the rotation speed with a current microcontroller. The MC uses a rotation-control signal that outputs 2 pulses in one cycle.

This allows customers to shorten the development time. 

Features

• Realizes low vibration and noise with a sine-wave PWM drive
• High efficient drive
• Controls the rotation speed
• Small mounting area

Additional features

Small surface-mounting type package

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

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 8-pole rotor can be applied to 12-pole rotor.

Applications

• Fans for home appliances
• Air conditioners, air purifiers, hot-water supply machines
• Fans for industrial equipment
• Refrigeration showcases and others
