Toshiba expands motor controller line

San Jose, Calif.—Toshiba America Electronic Components Inc. (TAEC) added three products to its line of motor drivers: a stepping motor driver (TB6560AHQ/AFG) and two H-bridge DC motor drivers (TB6559FG and TB6593FNG).

The TB6560AHQ/AFG is designed to control the two-phase bipolar stepping motors used in printers, where the driver's two-phase operation can provide smoother transition between motor speeds to prevent paper jams.

The TB6560AHQ/AFG is a pulse width modulation (PWM) controlled, chopper-type, sinusoidal, micro-step bipolar stepping motor driver. It supports the excitation modes 2-phase, 1-2-phase, 2W1-2-phase and 4W1-2-phase, as well as forward/reverse mode. The TB6560AHQ/AFG provides a low vibration, high-performance drive for two-phase bipolar type stepping motors using only one clock signal. The driver was developed in Toshiba's BiCD (bipolar/CMOS/DMOS) process.

The TB6559FG and TB6593FNG DC motor drivers target applications such as vending machines, gaming machines, printers and small appliances.

The TB6559FG full-bridge DC motor driver IC offers support for two motor control-operating modes, either internal constant current PWM (for Vref between 0V and 3V) or direct PWM (for Vref between 4.5V and VREG). The TB6593FNG motor driver IC has a very low R(on) of 0.35 ohms, which allows the device to provide high performance while drawing power at levels similar to a motor driver intended for battery-powered applications. The TB6559FG operates with an output current of up to 2.5 amps (peak) and supply voltages of up to 30 volts. The TB6593FNG operates with an output current of up to 3.2 amps (peak) and supply voltages of up to 13.5 volts. These devices were also developed in Toshiba's BiCD manufacturing process.

Pricing: The evaluation price in 10,000 unit quantities for the TB6560AHQ/AFG is $3.30 each, $0.62 for the TB6559FG and $0.66 each for the TB6593FNG.
Availability: Engineering samples of the TB6560AHQ/AFG are scheduled for availability in the fourth quarter 2007, with mass production scheduled to begin by end of year. Both the TB6559FG and TB6593FNG are currently in mass production.
