BD63801EFV-E2

Overview

The BD63801EFV-E2 is a bipolar stepper motor driver IC from ROHM Semiconductor, designed for CLK-IN drive methods. It features a rated output current of 0.8A and supports full step and half step modes. The device operates with a single power supply input ranging from 19V to 28V, with a maximum Vcc of 36V. It utilizes low on-resistance DMOS technology and includes protection circuits such as thermal shutdown (TSD), overcurrent protection (OCP), under-voltage lockout (UVLO), and over-voltage lockout (OVLO). The component is housed in a compact HTSSOP-B24 package.

Feature Summary

• Supports CLK-IN drive method with full step and half step operation modes
• Integrates comprehensive protection mechanisms including thermal shutdown, overcurrent, under-voltage, and over-voltage lockouts
• Utilizes low on-resistance DMOS technology for efficient power management
• Features a compact, thin, high-heat dissipation HTSSOP-B24 package with back-side heat radiation

Applications

• Bipolar stepper motor control systems
• Precision motion control applications requiring simple interface
• Devices supporting external DAC micro-stepping configurations

Procurement Notes

Verify the specific suffix E2 against official ROHM documentation to confirm pin compatibility and functional equivalence within the interchangeable product line. Ensure that the selected variant matches the required package type and thermal characteristics for your specific PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component for applications requiring a single-supply bipolar stepper driver with integrated protection features. Consider the 0.8A output current limit and the 19V to 28V operating voltage range when matching motor specifications. The CLK-IN interface simplifies control logic integration compared to more complex PWM-based drivers.

Part Context

This part belongs to the BD63801EFV series of stepper motor drivers manufactured by ROHM Semiconductor.
