Toshiba Adds to Line-up of DMOS FET Transistor Arrays with 1.5A Sink-Output Driver

Toshiba Corporation’s (TOKYO: 6502) Semiconductor & Storage Products Company today announced the addition of new packages to its line-up of new-generation highly efficient transistor arrays, the “TBD62064A series” and “TBD62308A series” with DMOS FET[1] type sink- output[2] driver, that have found wide application, including in motor and relay drives.
The new products, “TBD62064AFAG” and “TBD62308AFAG” are packaged in “SSOP24” surface-mount type, standard packages. Mass production starts today.

Following some reports from customers, Toshiba analyzed handling of the HSOP type surface-mount packages that it uses in its in-line packages, and has found that there can be difficulties with the flow of solder to the heat radiating fins during board mounting. In response, Toshiba has developed an SSOP type package with the same heat dissipation performance as the HSOP package. The SSOP has standard 1mm-pitch pins without the heat radiating fins, and achieves easy board mounting.

The new products are equipped with 4 channels of 50V/1.5A rated output, suitable for driving constant voltage unipolar stepping motors.

Toshiba adopted DMOS FET output drivers for its new products to secure the high efficiency customer requires to reduce power loss—DMOS FET do not require a base current, and can accept high current density per device area, keeping on-resistance low.

Main Features of New Products

High efficiency drive
“TBD62xxxA series” transistor arrays cut power loss by about 38%[3] compared with the “TD62xxxA series”.

High-voltage, large-current drive
The absolute maximum rating of the output is 50V/1.5A.

Packages to suit various needs.
The line-up includes DIP packages, where there is strong demand from the hobby goods, amusement and industrial equipment fields, and SSOP/HSOP packages that support high current (1.5A) drives and surface mounting

Applications

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)

Others
  • Absolute Maximum Ratings: Output current 1.5A / output voltage 50V (Same characteristics)
  • Input current of the new-generation products is lower, because base current is unnecessary.
  • Output voltage of the new-generation products necessary for the drive of the output current is lower than TD62xxxA series, because of the suppression of the on-resistance.
  • The package is standard 1mm- pitch type without heat radiating fins, suitable for board mounting.
