Toshiba 600V IPDs target BLDC motor drives
Additional devices offer a compact through-hole option for designers
Toshiba has extended its range of intelligent power devices (IPD) for brushless DC (BLDC) motor drives. The new devices are suited to use in pumps, air conditioning, ventilation, fans and other similar applications.
Complementing the TPD4163F and TPD4164F, the new products (TPD4163K and TPD4164K) use a HDIP30 through hole package measuring 32.8mm x 13.5mm x 3.525mm. This new package is said to reduce the PCB mounting area by over 20 percent, when compared to Toshiba’s DIP26 products such as TPD4123x, TPD4144x, and TPD4135x. This contributes significantly to reducing the space required for motor drive circuit boards.
In common with the earlier releases, the new IPDs are based upon 600V-rated IGBTs and include a matched gate driver to deliver an integrated solution in a compact package. The TPD4163K has a maximum DC current (IOUT(max)) rating of 1A and the more capable TPD4164K is rated at 2A. IGBT saturation voltage (VCEsat) of the devices is 2.6V and 3.0V respectively and the diode forward voltage (VF) is 2.0V and 2.5V.
The maximum supply voltage rating (VBB(max)) of both devices is now 600V which increases the design margin. This enhancement is useful in locations where mains power is variable or subject to fluctuations.
