Toshiba has launched two products for brushless DC (BLDC) motor drive applications including fan motors, ventilation fan, air conditioners, air cleaners, and pumps.
Each of the intelligent power devices (IPD) incorporate 600V-rated IGBTs and a matched gate driver as a one-chip solution in a single compact package. The output DC current (IOUT) rating of the TPD4163F is 1A while the TPD4164F is rated at 2A.
The two devices (TPD4163F and TPD4164F) have an IGBT saturation voltage (VCEsat) of 2.6V and 3.0V respectively, while the Diode forward voltage (VF) is 2.0V and 2.5V.
Both devices are housed in a miniature surface mount HSSOP31 package. With dimensions of just 17.5mm x 11.93mm x 2.2mm, the PCB footprint is reduced by around 63% when compared with Toshiba’s existing DIP26 package products. This makes a significant contribution to reducing the space required for motor drive circuit boards.
In addition, in geographic regions where the power supply is unstable, the supply voltage may fluctuate significantly. Therefore, to improve reliability, the supply voltage rating (VBB)has been increased from 500V to 600V to introduce more design margin.
To support the new devices, Toshiba has developed a reference design for BLDC sensorless brushless DC motor drive utilising the new TPD4164F and a microcontroller TMPM374FWUG.
