Toshiba Electronics Europe has announced a new stepping motor driver chip that is claimed to lower noise and vibration during motor operation. The TB67S209FTG supports high-speed, high-performance motor control in office automation, banking terminals and home appliance applications.
The TB67S209FTG reduces noise and vibration in stepper motor applications with efficient operation and accurate current control
The new IC achieves noise and vibration reduction by utilising Mixed Decay Mode MDM, a current adjustment function, which enables the control of the current and current change to the stepping motor by selecting the most appropriate MDM setting for the target motor.
The driver is said to offer a 50V maximum rating and is able to integrate low ON resistance MOSFETs for the motor output to operate at RON(typ.) 0.49 Ω. Maximum current rating is 4A.
The chip offers step resolutions of full, half, quarter, 1/8, 1/16 and 1/32 and features integrated error detection signal output function and provides thermal shutdown, over-current shutdown and under voltage lock out protection. Power on sequencing support is a standard feature.
The new controller is supplied in a small QFN package that will allow designers to reduce heat problems and simplify PCB design patterns for heat dissipation.
Mass production for this device has commenced. For more information, view the full Press release.
