Toshiba Releases TB62209F Motor Driver IC

March 26, 2001 by Jeff Shepard

Toshiba America Electronic Components Inc. (TAEC, Irvine, CA) introduced a motor driver IC, the TB62209F, that uses a new BiCD process, integrating bi-polar, CMOS and double-diffused MOS devices on a single chip. Toshiba claims that the new process and built-in field effect transistor (FET) output enables its new IC to achieve a low power consumption with an on-resistance of 0.5 ohms, a maximum voltage of 40V and an electric current of 1.5A. These features reduce the power consumption by a third of what Toshiba's current bipolar motor ICs offer.

The TB62209F is housed in a 36-pin HSOP with a 0.65mm pitch. The device features a micro-step decoder that enables it to rely on the clock signal to achieve smooth motor control, by generating the micro-step waveform from the clock signal. In addition, the stepping motor control circuit and driver circuit are integrated into a single package. Other features include the integration of Toshiba's selectable mixed decay mode technology, as well as protection circuits for high-temperature, over-current and power-supply monitoring. Furthermore, a caution-output pin warns of irregularities. The TB62209F is suitable for use in industrial applications and information equipment, including printers and facsimile machines.

Samples of the TB62209F will be available in May, 2001 at $3.70 each, with volume production scheduled to begin in June, 2001.
