Arrays feature industry-first 1.5A sink-output driver for wide range of high-voltage applications
SAN JOSE, Calif., – Toshiba America Electronic Components, Inc. (TAEC)*, a committed leader that collaborates with technology companies to create breakthrough designs, today announced it has expanded its offering of next-generation efficient transistor arrays. The TBD62064A and TBD62308A series features DMOS FET1 type sink-output2 drivers, and are the industry’s first3 transistor arrays with a 1.5A sink-output driver. 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 new 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 new transistor approach enables them to cut power losses by about 38 percent4.
The new 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.
“Implementing DMOS FET output drivers was essential to Toshiba’s achieving this power-loss reduction,” noted Deepak Mithani, senior director, Mixed Signal Business Unit, System LSI Group at TAEC. “They do not require a base current and can accept high current density per device area, thus keeping on-resistance low and providing high power efficiency. These products can also replace four low-power discrete MOSFETs for general-purpose power-switching applications that save cost and routing areas.”
The new 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.
Mass production of the TBD62064 and TBD62308A DMOS FET arrays is underway.
