Toshiba Electronics Europe (www.toshiba-components.com) is proud to announce the release of its two high-voltage, high current motor driver ICs, which are designed to simplify stepper motor-based designs in various industrial and office automation applications.
The TB62215FNG and TB62213FNG, based on a PWM constant current drive scheme, are single-chip two-phase bipolar stepper motor drivers that can deliver maximum motor output currents of 3.0A per phase and maximum motor output voltages of 40V.
The TB62215FNG operates with a clock-in decoder for clock input control, while the TB62213FNG has a control interface that makes use of phase input information provided by a host microcontroller.
Each driver has an on-chip voltage regulator to help create complete stepper motor control designs with the use of a single-motor power supply of as high as 40V.
Further flexibility in the design results from its capability to select two-phase, W1-2-phase, or 1-2-phase excitation modes.
A power-on-reset (POR) function and on-board thermal over-current shutdown help in minimizing component count and board space.
Manufactured through the company’s BiCD process, the TB62215FNG and TB62213FNG incorporate DMOS FETs as output power transistors.
Supplied in 48-pin HTSSOP packages, the motor driver ICs will be ideal to applications ranging from vending machines and office automation equipment to arcade games and card readers.
