Overview
The BD63715AEFV-E2 is a bipolar stepper motor driver from ROHM Semiconductor, designed for high-performance and reliable voltage applications. It features a rated output current of 1.5 A with a peak capability of 2 A. The device operates within a power supply voltage range of 19 V to 28 V, utilizing a single power supply input for simplified design. It supports CLK-IN drive mode and offers full, half, and quarter-step functionality via an internal DAC. Key electrical parameters include a typical output on-resistance of 0.95 Ω and a maximum operating temperature of +85 °C.
Feature Summary
- Supports multiple excitation modes including full, half, and quarter-step operation through built-in digital-to-analog conversion.
- Features freely adjustable current decay timing with linearly variable fast and slow decay ratios for optimized motor control.
- Integrates comprehensive protection mechanisms such as thermal shutdown, over-current protection, and under-voltage lockout.
Applications
- Precision positioning systems requiring micro-stepping capabilities
- Industrial automation equipment and motion control modules
- Office automation devices such as printers and scanners
Procurement Notes
Verify the specific suffix E2 against the manufacturer's official datasheet to confirm pin compatibility and functional equivalence. Ensure that the application environment remains within the specified -25 °C to +85 °C operating temperature range. Confirm that the system power supply strictly adheres to the 19 V to 28 V limits to prevent device damage or instability.
Selection Notes
Select this component when a bipolar stepper driver with integrated step generation and precise current control is required. The CLK-IN interface simplifies logic connections compared to traditional PWM inputs. Consider the single power supply architecture if board space and component count are critical constraints in the design.
Part Context
This part belongs to the BD63715 series of high-performance stepper motor drivers. It is distinguished by its ability to handle higher voltages while maintaining low standby current. The HTSSOP-B-28 package provides efficient thermal dissipation for continuous operation in compact electronic assemblies.
Replacement Considerations
The standard BD63715AEFV is the base model without the E2 suffix. Verify if the E2 designation implies specific packaging or automotive-grade qualification changes before substitution.
