Overview
The BD68710EFV-E2 is a bipolar stepper motor driver manufactured by ROHM Semiconductor. It features a rated power supply voltage of 36 V and a rated output current of 1.0 A. The device operates with an operating supply current of 2 mA. It supports load voltage ratings between 19 V and 28 V. The component is housed in a 28-lead HTSSOP-B package suitable for surface mount installation.
Feature Summary
- Low-power consumption design utilizing PWM current drive technology
- Supports free selection between fast decay and slow decay modes for current attenuation
- Utilizes PARA-IN driving method for input interface control
Applications
- Stepper motor control systems requiring low power consumption
- Motion control applications with bipolar stepper motors
- Devices requiring selectable current decay modes for torque optimization
Procurement Notes
Verify the specific suffix E2 against the official ROHM datasheet to confirm pinout and electrical characteristics match the target design. Ensure the HTSSOP-B-28 package dimensions align with the PCB footprint. Confirm that the 36 V rating and 1.0 A output current meet the system requirements without exceeding thermal limits in the intended enclosure.
Selection Notes
Select this component when a bipolar stepper driver with low quiescent current is required. The PARA-IN interface simplifies logic control compared to complex step/dir interfaces. Consider the thermal performance of the HTSSOP-B-28 package if high ambient temperatures are expected, as the device dissipates heat based on the load current and voltage drop across the internal H-bridge.
Part Context
This part belongs to the BD68710 series of bipolar stepper motor drivers from ROHM. It is designed for applications where power efficiency and precise current control are priorities. The series typically integrates protection features common to modern motor drivers, though specific details must be confirmed via the manufacturer's documentation.
Replacement Considerations
Check for direct cross-references in ROHM's product lineup. Similar bipolar drivers may include the BD68715 series for higher current requirements or different voltage ratings. Verify compatibility of the PARA-IN interface with existing control logic before substituting.
