BD63520AEFV-E2

Overview

The BD63520AEFV-E2 is a micro-stepping stepper motor driver manufactured by ROHM Semiconductor. It supports 1/16 µ-step resolution for precise motion control. The device features a rated supply voltage of 36V and delivers a DC output current of 2.0A. It operates within a load voltage range of 8V to 28V. The component utilizes an HTSSOP-B-28 package with SMD/SMT mounting style. Power dissipation is rated at 4.7W, with a quiescent supply current of 2mA. Operating temperatures span from -25°C to +85°C.

Feature Summary

Supports high-resolution 1/16 micro-stepping for smooth motor operation
Integrates low-power bipolar PWM constant current drive architecture
Provides dual-channel output capability for bipolar stepper motors

Applications

Industrial automation equipment requiring precise positioning
Motion control systems utilizing small to medium-sized bipolar stepper motors
General purpose motor driver circuits in consumer electronics

Procurement Notes

Verify the specific suffix E2 against official ROHM documentation to confirm pinout compatibility and thermal characteristics. Ensure the HTSSOP-B-28 package dimensions align with PCB layout requirements. Confirm moisture sensitivity level handling procedures are followed during assembly to prevent package damage. Cross-reference the 36V rating with system power supply limits to avoid overvoltage conditions.

Selection Notes

Select this component when 1/16 micro-stepping resolution is required for reduced vibration and noise. The 2.0A output current suits applications driving small to medium bipolar stepper motors. Consider the 36V supply rating for systems requiring higher voltage headroom. The integrated PWM constant current drive simplifies design compared to discrete solutions. Evaluate the -25°C to +85°C operating range against environmental constraints.

Part Context

This part belongs to ROHM's series of micro-stepping stepper motor drivers designed for efficient motion control. It integrates control logic and power stages into a single IC, reducing external component count. The BD63520AEFV-E2 variant specifically targets applications needing high resolution and moderate current capacity within a compact surface-mount package.
