TB62205F

www.DataSheet4U.com TB62205F TOSHIBA BiCD Process Integrated Circuit Silicon Monolithic TB62205F Single-Stepping Motor Driver IC with Dual DC/DC Converter Driven by Chopper Micro-Step Pseudo Sine Wave The TB62205F is a single-stepping motor driver with dual DCDC converter driven by chopper micro-step pseudo sine wave. To drive a two-phase bipolar-type stepping motor, a 16-bit latch and a 16-bit shift register are built in the IC. The TB62205F is suitable for driving stepping motors at high efficiency and with low-torque ripple, and supports Selectable Mixed Decay Mode for switching the attenuation ratio at chopping. Also, the IC incorporates two DCDC converters, enabling two individually configurable power supplies. Features One stepping motor driven by micro-step pseudo sine wave is controlled by a single driver IC Weight: 0.79 g (typ.) Enables to drive two-way supply voltage using a pair of step-down DC/DC converters Monolithic Bi-CMOS IC Low ON-resistance of Ron = 0.7 Ω (@Tj = 25°C, 1.0 A: typ.)
