Toshiba’s new eight-channel high- and low-side switches boost efficiency, reduce size and extend operating temperature

Toshiba Electronics Europe has launched two intelligent power products to control the driving of resistive and inductive loads including motors, solenoids and lamps in applications such as programmable logic controllers within industrial equipment.

The power switch products both comprise eight channels and are high-side (TPD2015FN) and low-side (TPD2017FN) switches. Both devices benefit from Toshiba’s latest analogue device process (BiCD) that combines bipolar, CMOS, and DMOS technologies.

Both of the products are housed in a small 0.65mm pitch SSOP30 package that measures just 9.7 x 7.6 x 1.2mm. This offers a reduction of around 29 per cent in mounting area and 20 per cent in height over the SSOP24 package (13.0 x 8.0 x 1.5mm) that is used for current products such as the TPD2005F and TPD2007F, thereby reducing the size of designs.

With regard to the electrical performance, the on-resistance (RDS(ON)) of both devices is 0.4Ohm – more than 50 per cent less than that of Toshiba’s current products, significantly enhancing operating efficiency and thermal performance, claimed the company. The rugged power switches are able to operate at temperatures (Topr) from -40 degree C to +110 degree C with a junction temperature (Tj) as high as +150 degree C, ensuring their suitability for challenging industrial environments.

In addition, both products have built-in over-current protection circuits and over-temperature protection circuits, ensuring the reliability of equipment they are used in.

Toshiba Electronics Europe is the European electronic components business of Toshiba Electronic Devices and Storage Corporation. TEE offers European consumers and businesses a variety of hard disk drive (HDD) products plus semiconductor solutions for automotive, industrial, IoT, motion control, telecoms, networking, consumer and white goods applications. The company’s portfolio encompasses power semiconductors and other discrete devices ranging from diodes to logic ICs, optical semiconductors as well as microcontrollers and application specific standard products (ASSPs) among others.
