TB62217AFG Datasheet DC-dc Converter And Reset Function-ic

Manufacturer: Toshiba

Overview: TB62217AFG TOSHIBA BiCD Process Integrated Circuit Silicon Monolithic TB62217AFG PWM drive Stepping Motor Driver / Brush DC Motor Driver Selectable, DC-DC Converter and Reset function IC The TB62217FG 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 a two-phase bipolar-type stepping motor, a 16-bit latch and 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. By equipping the stepping motor driver with Selectable Mixed 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 a built-in timer that starts running when the IC is supplied with power, the IC can be used in resetting (initializing) external devices. Weight: 0.45 g (typ.
