Product Summary
The TB62237BFG is a dual stepping motor driver driven by PWM chopper micro step, with 3-channel step-down DC-DC converters and an external-IC reset function. To drive two stepping motors of two-phase bipolar type, a 16-bit latch and a 16-bit shift register are built into the IC. The TB62237BFG is suitable for driving stepping motors with low-torque ripple in a highly efficient manner. In addition, a signal axis can be switched to serve as a PWM driver for two DC motors.
