PWM drive Stepping Motor Driver / Brush DC Motor Driver Selectable, DC-DC Converter

and Reset function IC

chopper micro step, with 3- channel step-down DC-DC converters and

an external-IC reset function.

a 16-bit shift register are built into the IC. The IC 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.

Decay Mode for switching the attenuation ratio during chopping, and

also equipping it with a DC-DC converter, it is possible for the IC to

supply external voltage.

with power, the IC can be used in resetting (initializing) external

devices.

Features

thermal setting is designed to be within the prescribed thermal range, the initial torque current can be used as the

normal operating current.
