Toshiba Electronics Europe has expanded its line up of High Voltage Intelligent Power Devices (HV-IPD) with the addition of a motor driver IC in a compact surface mount package that is rated to 600V. The TPD4152F enables a square-wave speed control of small BLDC electric motors. It is aimed at applications including air conditioners, air purifiers, fans, ventilators and water heaters.

The TPD4152F has a maximum current rating of 0.7A. It 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 17.5x8.4x2mm 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 for testing with the TPD4152F.
