Transistor Arrays with DMOS FET Source-Output Driver

October 05, 2015 by Jeff Shepard

Toshiba Corporation's Semiconductor & Storage Products Company announced the launch of a new generation of highly-efficient transistor arrays, the TBD62783A series with a DMOS FET type source-output driver. The new series succeeds the TD62783 series of bipolar transistor arrays, which have found wide use in applications including LED drives. All four products in the TBD62783A series are available as samples, and mass production will start in December 2015. The new transistor arrays are the first DMOS FET source-output drivers.

Toshiba will also launch the TBD62083A series with a DMOS FET type sink- output driver, successor to the TD62083 series of bipolar transistor arrays for applications including motors, relays and LED drives. All eight products in the TBD62083A series went into mass production on September 30.

Demands from customers developing systems such as power supply and ON/OFF controls that combine source output and sink output products are increasing. With the launch of the new devices, Toshiba provides a DMOS FET transistor array for both output types.

Toshiba adopted DMOS FET type output drivers to secure the high efficiency that customers need to cut power loss—DMOS FET do not require a base current, and can accept high current density per device area, keeping on-resistance low. Toshiba has also applied the latest BiCD technology. The company has positioned this as the future mainstream for analog ICs fabricated on its standard 8-inch manufacturing line, the wafer size widely used in the industry for mass production.

Main features of these new products include: High efficiency drive, TBD62xxxA series transistor arrays cut power loss by about 40% compared with the TD62xxxA series. High-voltage, large-current drive, The absolute maximum rating of the output is 50V/0.5A. and Packages to suit various needs, Available packages are DIP, SOP/SOL for surface mounting and small SSOP (0.65mm pitch) for space saving.

Applications are expected to include: amusement equipment (pachinko and slot machines), home appliances (air-conditioners and refrigerators) and industrial equipment (vending machines, banking terminals such as ATMs, office automation equipment, and factory automation equipment).
