The single-channel interface driver offers significant advantages in reducing component counts, achieving smaller printed circuit boards and minimising EMI.
IFDs connect the main CPU to subsystems in home appliance, automotive and office equipment applications.
The IFD receives 3 to 5V signals from the CPU and amplifies them to the voltage level required by subsystems such as switch relays, stepping motors, thermal heads and LEDs.
However, the large number of outputs in conventional IFD ICs make them heat sources when multiple subsystems operate simultaneously.
This heat problem can be a factor in reducing the operating output current.
Toshiba's single-channel IFD is able to realise lower component counts, reduce the chip mounting area and disperse heat from complex circuits.
The single-channel IFD also has the advantage of shorter wiring for the power line as they can be positioned nearer to the load than conventional arrays.
This, in turn, contributes to a reduction in EMI.
Samples of the new ICs are available now, with mass production targeted for the end of March 2001.
By 2002 Toshiba aims to produce one million pieces per month.
