Toshiba Launches 600V Sine-Wave PWM Driver IC for Three-Phase Brushless Motors
October 1, 2019
IRVINE, Calif. – 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.
