Toshiba releases small 600V devices for brushless DC motors
Surface mount type small package helps reduce mounting area
Toshiba has launched two 600V small intelligent power devices for brushless DC motor drive applications such as air conditioners, air cleaners, and pumps.
The TPD4163F and TPD4164F, which have output current (DC) ratings of 1A and 2A, respectively, are housed in a surface mount type HSSOP31 package, which reduces the mounting area by approximately 63 percent against Toshiba’s previous products. This makes smaller motor drive circuit boards possible, and also reduces the height of the motor.
As power supply voltage may fluctuate significantly in regions with unstable power supply, the voltage has been increased from the 500V of Toshiba’s previous products to 600V, which improves reliability.
A Reference Design for Sensorless Brushless DC Motor Drive Circuit that uses the functions of the new TPD4164F with a TMPM374FWUG microcontroller with vector control engine is available on Toshiba’s website.
