Toshiba Electronics Europe (TEE) has announced two new high-voltage, high-current motor driver ICs that will simplify stepper motor-based designs in a variety of office automation and industrial applications. Based around a PWM constant current drive scheme, the TB62213FNG and TB62215FNG are single-chip two-phase bipolar stepper motor drivers capable of delivering maximum motor output voltages of 40V and maximum motor output currents of 3.0A per phase. The TB62213FNG operates with a control interface that uses phase input information supplied by a host microcontroller, while the TB62215FNG has a clock-in decoder for clock input control.

Each of the new drivers features an on-chip voltage regulator that facilitates the creation of complete stepper motor control designs using a single motor power supply of up to 40V. Further design flexibility results from the ability to select 2-phase, 1-2-phase or W1-2-phase excitation modes. On-board thermal and overcurrent shutdown and a power on reset (POR) function helps to keep board space and component count to a minimum.

Manufactured using Toshiba’s proprietary BiCD process, the TB62213FNG and TB62215FNG incorporate DMOS FETs as output power transistors. The ICs, which are supplied in 48-pin HTSSOP packages, will suit applications ranging from office automation equipment and vending machines to arcade games and card readers.
