Overview
The BD68720EFV-E2 is a bipolar stepper motor driver from ROHM Semiconductor, rated for a maximum supply voltage of 36 V and delivering an output current of 2.0 A. It operates within a load voltage range of 19 V to 28 V and features a typical on-resistance of 0.65 Ω. The device supports full, half, and quarter-step resolutions with adjustable FAST/SLOW decay ratios. It functions in an ambient temperature range of -25°C to +85°C and is housed in a 28-pin HTSSOP-B package.
Feature Summary
- Supports PARA-IN drive mode with PWM constant current control
- Allows free setting of FAST DECAY and SLOW DECAY ratios
- Integrates protection circuits including thermal shutdown and over-current protection
Applications
- Industrial automation equipment
- Office automation devices
- General-purpose motion control systems
Procurement Notes
Verify the specific suffix E2 against the manufacturer's datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the HTSSOP-B-28 package dimensions align with your PCB footprint. Confirm that the operating temperature range meets your environmental specifications before finalizing procurement.
Selection Notes
Select this component when a 36 V rating and 2.0 A continuous output are required for bipolar stepper motors. The adjustable decay ratio offers flexibility for optimizing torque and noise performance. Consider the integrated protection features for robust operation in industrial environments without external circuitry.
Part Context
This part belongs to ROHM's series of low-consumption bipolar stepper motor drivers. It utilizes DMOS output technology to achieve high efficiency and reliability. The device is designed for single power supply input, simplifying system architecture compared to dual-supply solutions.
Replacement Considerations
The BD68620EFV-E2 is a related model in the same family but offers different output characteristics and package options. Verify compatibility regarding current ratings and interface signals before substitution.
