The TPD4207F combines controller and driver logic, high-voltage MOSFETs in a three-phase bridge output, bootstrap diodes and comprehensive protection functionality. It simplifies the implementation of high voltage pulse width modulation control in BLDC applications ranging from home appliances to industrial pumps and fans as full control of a BLDC motor is achieved by simply applying signals from a host microcontroller or motor controller IC to the TPD4207F inputs.

Toshiba has used its high-voltage Super Junction MOSFET technology (DTMOS IV) and driver IC in a multi-chip configuration. The package has been designed by separating all small signal pins from the power pins and this has allowwed other functions such as over-current and under-voltage protection and thermal shutdown to be included.

The TPD4207F is supplied in a compact SOP-30 package with a footprint of only 20.0mm x 11.0mm x 2.0mm. Typical on resistance is just 0.44Ω. Suitable for high-efficiency, low-noise sine-wave motor control, the new HV-IPD allows dead-time to be configured from a minimum of 1.0us.
