Toshiba America Electronic Components Inc. has introduced what it describes as the industry's first transistor arrays with a 1.5A sink-output driver. The TBD62064A and TBD62308A series packs DMOS FET type sink-output drivers that promises to deliver remarkable efficiency.

The series, including the first two products (TBD62064AFAG and TBD62308AFAG), are equipped with four channels of 50V/1.5A output, suitable for driving constant-voltage unipolar stepping motors and relays, and for multi-channel, general-purpose, low-side driver power applications.

Replacing the previous-generation TD62064A and TD62308A series of bipolar transistor arrays, the TBD62064A and TBD62308A series of arrays are available in the same package and pin configurations and provide the same functionality as the predecessors. Moreover, the transistor approach enables them to cut power losses by about 38%.

TBD62064A, TBD62308A

The TBD62064A and TBD62308A series, with control inputs of up to 25V, differ by their use of active high or low control logic, respectively. Both series include four common cathode clamp diodes that are suitable for, but not limited to, motor, relay and lamp type of low-side driver applications. The four channels can also be paralleled to increase the current driving capability for higher power applications, where designers pay attention to the channel tolerance for power balancing.

The series are manufactured using the latest 130nm BiCD process technology and are available in either HSOP16, DIP16 or SSOP24 packages. The products are suitable for high-voltage motor and relay driving applications such as home appliances (air conditioners and refrigerators) and industrial equipment, such as vending machines, banking terminals, and factory and office automation equipment, detailed the company.

Mass production of the TBD62064 and TBD62308A DMOS FET arrays is underway.
