BD6607KN-E2

Overview

The BD6607KN-E2 is a fully integrated system motor driver manufactured by ROHM Semiconductor, designed for low-voltage applications. It operates within a supply voltage range of 1.8V to 5V and features a 64-pin UQFN (8x8) surface-mount package. The device incorporates two H-bridge driver circuits utilizing power DMOS transistors with a typical on-resistance of 0.70Ω. Additionally, it includes two comparator circuits specifically configured for motor back-electromotive force (BEMF) voltage detection. The component supports a maximum output current of 1A per channel and functions within an operating temperature range of -25°C to +75°C.

Feature Summary

• Integrates dual H-bridge driver circuits with low ON-resistance power DMOS outputs
• Includes dedicated comparator circuits for accurate BEMF voltage sensing
• Supports parallel operation for enhanced current handling capabilities

Applications

• Brushless DC motor control systems requiring BEMF feedback
• Low-voltage portable electronic devices
• Integrated motion control modules

Procurement Notes

Verify the obsolete status of this component before design finalization, as availability may be limited to existing stock or last-time buys. Confirm that the 64-pin UQFN footprint matches your PCB layout constraints. Ensure the 1.8V to 5V supply range aligns with your system's power architecture. Check for moisture sensitivity classification requirements during storage and reflow soldering processes. Validate that the thermal performance of the UQFN package meets your application's heat dissipation needs.

Selection Notes

Select this component when a compact, fully integrated solution for low-voltage BLDC motors is required. The inclusion of internal BEMF comparators reduces external component count compared to discrete driver solutions. Consider the 64-pin package size if space is constrained but multiple bridge outputs are needed. Evaluate the 0.70Ω typical resistance against efficiency requirements. This part is suitable for applications where system-level integration simplifies the bill of materials.
