A new intelligent power device includes safety features such as under-voltage and thermal shutdown
Toshiba Electronics has launched a new intelligent power device (IPD) for space-constrained brushless DC (BLDC) motor drive applications such as air conditioners, air purifiers, and pumps. The product comes fitted with a range of safety features including over-current, under-voltage and thermal shutdown. Additionally, an external signal can be applied to the SD pin to control the behaviour of the output stage. The DIAG output pin provides the status of the safety conditions.
The new IPD (TPD4165K) has an increased maximum output current of 3A, compared with the 2A rating of Toshiba’s existing products like TPD4163K, or TPD4164K. This extends the range of supported equipment and allows use in higher power applications. The device is suitable for sine-wave drive.
As power supply voltage may fluctuate significantly in some regions where the IP could be used, the absolute maximum voltage rating (VBB) has been increased to 600V to enhance long-term reliability. This represents a 20% increase over Toshiba’s previous products (TPD4123K, TPD4123AK, TPD4144K, TPD4144AK, TPD4135K, TPD4135AK).
The new TPD4165K is housed in a through-hole HDIP30 package. This has a 21% smaller footprint than the DIP26 package used for many of Toshiba’s previous products, simplifying the design process for challenging space-constrained applications. The new device measures just 32.8mm x 13.5mm x 3.525mm. It supports either a three-shunt or single-shunt resistor circuit for current sensing. Shipments of the new device are starting immediately.
