Overview
The BD63511EFV-E2 is a bipolar stepper motor driver and controller from ROHM Semiconductor, housed in a 28-pin HTSSOP-B package. It supports a supply voltage range of 8 V to 28 V with a maximum load voltage of 36 V. The device delivers a continuous output current of 1 A and a peak current of 1.5 A. It features PWM interface control with configurable step resolutions including full, half, quarter, and sixteenth microstepping. Operating temperature spans -25°C to +85°C, with power dissipation rated at 4.7 W.
Feature Summary
- Integrates control logic and power stages for bipolar stepper motors
- Supports multiple excitation modes via internal DAC
- Allows adjustable fast/slow decay ratio settings
- Operates on a single system power supply
Applications
- Bipolar stepper motor control systems
- Brushed DC motor drivers
- Industrial automation equipment
- Precision motion control applications
Procurement Notes
Verify the specific suffix E2 against the manufacturer's latest datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure thermal management solutions accommodate the specified power dissipation limits within the operating temperature range. Confirm RoHS compliance status through official documentation before integration.
Selection Notes
Select this component when designing systems requiring integrated microstepping capabilities up to 1/16 resolution. It is suitable for applications needing a single-supply architecture with high voltage tolerance up to 36 V. Consider the HTSSOP-B-28 package constraints for PCB layout and thermal performance during the selection process.
Part Context
This part belongs to ROHM's µ-step series of stepper motor drivers. It is designed as a low-power, constant-current driver utilizing DMOS technology. The device simplifies system design by combining driver and controller functions into a single surface-mount component, reducing external component count.
Replacement Considerations
The BD63510AEFV-E2 is a related variant within the same family. Verify compatibility regarding maximum voltage ratings and power dissipation specifications before substitution.
