Datasheet

Eleven products have been added to Toshiba Electronics Europe's line-up of new-generation transistor arrays equipped with DMOS FET outputs, capable of delivering high-voltage, large-current drive up to 50V/0.5A. The new devices expand the 37 products that are already part of the TBD62xxxA series, which have found wide application in areas including motors, relays, LEDs, and level shifters for control communication lines.

The 18 new devices meet customer requirements for a wider variety of input and output methods and functions. Current products are mainly High-active (H-active) type products where the output is turned on when the input is high. Toshiba is now adding Low-active (L-active) products where the output is turned on if the input is low. Due to their open-drain configuration, L-active products are well suited to level shifters for control and communication lines in industrial equipment and home appliances.

Toshiba is also adding the TBD62381A series, which reduces power consumption by modifying the characteristics of the TBD62083A series. The next-gen transistor arrays in the TBD62XXX series reduce power by approximately 40% when compared to the TD62XXX series.

The new devices offer two output types: a source output for switching power supplies and a sink output used for ON / OFF control. Dynamic control of LED matrices can be achieved by combining source and sink output types.

The new line-up includes DIP packages, which are popular in industrial equipment; SOL packages that support surface mounting, and tiny SSOP packages (0.65mm pin pitch) that deliver space savings in set-top products.
