TB62209F is a stepping motor driver IC from Toshiba. This driver uses PWM chopper type micro-step pseudo sine wave to drive two-phase stepping motor. It has the advantages of low torque ripple and low harmonic.
The TB62209F is a monolithic BiCD processor IC designed to drive two-phase stepping motors with low-torque ripples and high efficiency. It integrates a decoder for CLK input in micro-steps, facilitating the use of micro-step pseudo sine waves which are optimal for driving stepping motors at low oscillation.
