ROHM Stepper Motor Driver IC 28-Pin VQFN BD63621MUV-E2 36V, 2.0A

The ROHM BD63621MUV-E2 is a high-performance stepper motor driver IC in a 28-pin VQFN package, designed for precise bipolar low current consumption operation using PWM control. With a maximum supply voltage of 36V and an output current capability of 2.0A, this IC is well suited for industrial, automation, robotics, and embedded motor control applications requiring compact and efficient stepper motor driving.

This driver IC features a CLK-IN input mode and provides multiple excitation modes including full step, half step, and quarter step, selectable via an internal DAC. This versatility ensures fine motor control and smooth rotation operations.

Advanced current decay control allows adjustment of the FAST DECAY and SLOW DECAY ratio without limitation, enabling the most effective current regulation and reducing motor noise and heat dissipation.

Additional integrated functions include a built-in spike noise cancel function to improve electromagnetic compatibility, power save modes to reduce energy consumption, and a logic input pull-down resistor for stable input signal handling. The power-on reset and thermal shutdown circuits provide robust protection and reliable startup.

Safety is enhanced with adjacent pins short protection that safeguards against accidental short circuits during device operation. The IC's compact 28-pin VQFN package makes it ideal for modern PCB layouts with space constraints.

The driver IC supports multiple step modes through a built-in DAC for flexible motion control. Thermal shutdown and short-circuit protection increase reliability in harsh industrial environments. Designed to optimize power consumption with PWM constant current operation and power save functionality.

Suitable for applications including industrial automation, robotics, and motor control systems. Explore more Motor Driver ICs and power management solutions available for your industrial and manufacturing needs at EnvMart.
