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

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.

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.
