Marktech Introduces Toshiba's 2-phase Bipolar Driving Stepping Motor Drivers with Low On-Resistance and High Thermal Dissipation

Latham, New York: Marktech introduces the Toshiba TB6560HQ/FG 2-phase Bipolar Stepping Motor Drivers. There are very few drivers currently available on the market for 2-phase bipolar stepping motors that have a high current rating in excess of 2A for use in office automation and industrial equipment. Because heat that is generated by a high current can present significant problems for these types of applications Toshiba has developed the new TB6560HQ/FG stepping motor drivers that combine low on-resistance through the use of a BiCD process with thermally dissipative package, making it possible to dramatically reduce heat generation. These new devices also enable micro-step driving in support of microcontroller-less applications using CLKin control. They also support both 2-phase/1-2-phase/W1-2-phase/2W1-2-phase excitation modes and forward/reverse mode and is capable of low-vibration, high-performance driving of 2-phase bipolar type stepping motors using only a clock signal.

o Single-chip bi-polar sinusoidal micro-step stepping motor driver
o Low on-resistance (upper and lower sum) = 0.6W(HQ)/0.75W(FG)
o High allowable loss package: HQ:HZIP25, FG:THQFP64
o Input voltage (high) = Compatible with 3.3V or 5V
o Motor power supply VM = Compatible with 5V, 12V, or 24V
o Enables micro-step driving (2W1-2 phase excitation)
o Enables setting of current attenuation and supports high speed rotation
o CLKin type available, enabling motor driving by a single pin input (RESET and ENABLE pins used during startup)
o Forward and reverse rotation control available
o Equipped with reset and enable pins
o Built-in overheat protection circuit
