600V sine wave PWM driver IC protects against voltage fluctuations

Expanding the TB67B000 series of drivers which deliver highly energy efficient motor drive and noise reduction in a single, integrated package, Toshiba Electronics Europe has introduced a three-phase brushless motor driver for home appliances such as air-conditioners and air-purifiers.

The high voltage TB67B000AHG driver IC is pin-compatible with the current 500V TB67B000HG and can be used as a replacement or upgrade to provide greater resilience to voltage fluctuations. The motor drive output can generate either sine-wave PWM signals or wide-angle trapezoidal commutation at frequencies between 14kHz and 23kHz, for low-noise, low vibration operation.

The device integrates a 600V/2A IGBT three-phase bridge and motor control IC into a 32.8 x 13.5mm HDIP30 package. This saves board space and system cost, says Toshiba. Error detection functions including a current limiter, thermal shutdown, under-voltage lockout (UVLO) and motor lock detection are also integrated in the compact package.

Toshiba is also developing another 600V driver (TB67B000AFG) that is housed in a small 34-pin HSSOP that includes a heat sink.
