BD63960EFV-E2

Overview

The BD63960EFV-E2 is a bipolar stepper motor driver from ROHM Semiconductor, designed for single power supply operation within a voltage range of 19 V to 28 V. It delivers a maximum output current of 1.5 A and features an operating supply current of 2.7 mA. The device supports step modes including full, half, quarter, and eighth steps, with adjustable mix decay functionality. It operates reliably between -25°C and +85°C and is housed in a compact HTSSOP-B-24 package.

Feature Summary

• Supports eighth-step driving via built-in 3-bit DAC for high-resolution motion control
• Enables flexible current decay control through selectable mix decay ratios
• Integrates comprehensive protection circuits including thermal shutdown, overcurrent, undervoltage lockout, and overvoltage output OFF

Applications

• Precision positioning systems requiring micro-stepping capabilities
• Industrial automation equipment utilizing bipolar stepper motors
• Office automation devices such as printers and scanners
• Medical instrumentation requiring controlled motion profiles

Procurement Notes

Verify the complete part number including the suffix to ensure correct packaging and specifications. Confirm that the application voltage remains within the 19 V to 28 V range to prevent damage. Ensure proper thermal management is implemented due to the surface mount package design. Check for moisture sensitivity handling requirements during storage and assembly processes.

Selection Notes

Select this component when a single power supply solution is required for bipolar stepper motors up to 1.5 A. Consider the HTSSOP-B-24 package for space-constrained designs. Evaluate the need for eighth-step resolution and mix decay control for smooth operation. Verify compatibility with CLK-IN interface signals for integration into existing control architectures.

Part Context

This driver belongs to the BD63960 series of stepping motor drivers. It is part of ROHM's portfolio of PMIC solutions focused on motor control. The series emphasizes low power consumption and high reliability for embedded motion applications. It complements other drivers in the lineup offering different current ratings and voltage ranges.

Replacement Considerations

The BD63860EFV-E2 serves as a higher-current alternative within the same family, supporting up to 2.5 A output. Both devices share similar interface types and protection features but differ in current capacity and package size. Verify pin compatibility and thermal performance when substituting.
