Overview
The BD63710AEFV-E2 is a high-performance bipolar stepper motor driver manufactured by ROHM Semiconductor. It operates within a power supply voltage range of 19 V to 28 V and delivers a maximum output current of 700 mA. The device features a CLK-IN interface and supports full, half, and quarter-step excitation modes via an internal DAC. It utilizes a PWM constant current control method with adjustable fast/slow decay ratios. The component is housed in a 28-pin HTSSOP-B package and functions reliably across an operating temperature range of -25°C to +85°C.
Feature Summary
- Supports multiple excitation modes including full, half, and quarter-step operation through built-in digital-to-analog conversion.
- Enables precise motor control via adjustable linear mixing of fast and slow current decay modes.
- Integrates comprehensive protection mechanisms such as thermal shutdown, over-current protection, and under-voltage lockout.
Applications
- Precision positioning systems requiring stable stepper motor control
- Industrial automation equipment utilizing bipolar stepper motors
- Office automation devices needing low-power motion control solutions
Procurement Notes
Verify the specific suffix E2 to confirm the tape and reel packaging configuration and RoHS compliance status. Ensure the input signal timing aligns with the CLK-IN drive mode requirements specified in the official datasheet. Confirm that the system power supply remains within the 19 V to 28 V operational window to prevent under-voltage lockout or over-voltage damage during procurement validation.
Selection Notes
Select this component when a single power supply solution is required for both logic and motor drive circuits. It is suitable for designs needing integrated spike noise cancellation without external filters. Choose this driver for applications demanding flexible step resolution and adjustable decay characteristics to optimize torque and vibration performance in compact SMD form factors.
Part Context
This part belongs to the BD63710A series of high-reliability stepping motor drivers designed for 36 V withstand voltage environments. It is part of ROHM's portfolio of PMIC motor controllers aimed at reducing system complexity by integrating control logic and power stages into a single HTSSOP-B package.
Replacement Considerations
The BD63715AEFV-E2 serves as a verified substitute offering higher output current capability while maintaining identical pinouts and package dimensions. Verify compatibility regarding current handling requirements before substitution.
