High-integration power device handles 600V square-wave motor drive

September 03, 2015 // By Graham Prophet
The high voltage intelligent power device (IPD) is rated to 600V and 0.7A, in a compact surface-mount package. TPD4152F enables a square-wave speed control of small brushless DC (BLDC) electric motors for units such as air conditioners and fans.

The TPD4152F contains a PWM circuit, 3-phase decode circuit, level shift high side driver, low side driver and IGBT outputs. The device is housed in a 31 pin SMD-type package (HSSOP31) that separates low voltage signal pins from high voltage power pins. It measures 17.5 x 8.4 x 2 mm and occupies 60% less board mounting space than existing Toshiba IPDs in a DIP26 package and equivalent competing products. The TPD4152F also features over-current and under-voltage protection and thermal shutdown circuitry. An evaluation board is available.
