Toshiba Launches 600V Sine-Wave PWM Driver IC for Three-Phase Brushless Motors

Toshiba America Electronic Components, Inc. (“Toshiba”) has launched the “TB67B000AHG,” a new three-phase brushless motor driver for home appliances such as air-conditioners, air-purifiers, dehumidifiers, and ceiling fans.

The new driver is a high-voltage addition to the “TB67B000 series,” which realizes highly efficient brushless motor drive and noise reduction in a single package.

Demand is growing, particularly in emerging economies, for high-efficiency three-phase brushless fan motors that can reduce energy consumption and manage fluctuations in power voltage. Such motors require higher-voltage PWM driver ICs to maintain high product reliability.

Toshiba’s newly developed 600V TB67B000AHG driver IC is pin-compatible with the current 500V TB67B000HG and can easily replace it. Toshiba is also developing the more compact version “TB67B000AFG” in a small 34-pin HSSOP1 package which will be available in November 2019.

Main Features

600V rating boosts product reliability

Ensures products with greater resilience to voltage fluctuations than the current 500V TB67B000HG. Pin compatibility realizes easy replacement of the current IC.

Realizing sine-wave PWM drive with a rating of 600V/2A in a single package

Sine-wave motor control IC and IGBT (rating of 600V/2A) are integrated in a single package. This reduces the size of mounting area and board layout, and contributes to overall system cost reduction.

Low noise and low vibration

Use of a sine-wave drive system with a smooth current waveform reduces noise and achieves less vibration than motors with a rectangular wave drive system.

Applications

Home appliances such as air-conditioners and air-purifiers, dehumidifiers, DC fans, ceiling fans, and other industrial equipment.
