BD65494MUV-E2

Overview

The BD65494MUV-E2 is a single-channel H-bridge motor driver manufactured by ROHM Semiconductor, designed for low-power applications. It operates with a power supply voltage range of 2.0V to 9.0V and supports a Vcc range up to 10V. The device delivers a DC output current of 1.0A with a peak current capability of 2.5A. Key electrical parameters include a typical output on-resistance of 0.55Ω and a standby current of 0μA. It features high-speed switching with turn-on times of 200ns and turn-off times of 60ns. The component functions within an operating temperature range of -30°C to +85°C and is housed in a compact VQFN-16 package measuring 3.0x3.0mm.

Feature Summary

• Integrates a single-channel full ON drive H-bridge utilizing low on-resistance DMOS outputs for efficient power management.
• Supports charge-pump-less operation through p-channel DMOS transistors for the upper side bridge configuration.
• Includes built-in protection mechanisms such as Under Voltage Locked Out (UVLO) and Thermal Shutdown circuits.
• Offers selectable drive modes via EN/IN or IN/IN input configurations for flexible control integration.

Applications

• Lens drivers for single-lens reflex cameras
• Mobile device components requiring small surface mount solutions
• Household appliance motor control systems

Procurement Notes

Verify the specific suffix E2 when ordering to ensure compliance with RoHS standards and lead-free requirements. Confirm that the application environment remains within the specified commercial temperature range of -30°C to +85°C, as this component is not rated for automotive use. Ensure the load voltage does not exceed 9V and the supply voltage stays within the 2.0V to 9.0V operational window to maintain device integrity and performance specifications.

Selection Notes

Select this component for applications requiring a compact, single-channel H-bridge solution with minimal standby power consumption. It is suitable for systems where high-speed switching is necessary but peak currents remain below 2.5A. Consider the VQFN-16 package for space-constrained designs. Do not use if automotive qualification or extended temperature ranges beyond 85°C are required, as alternative series parts should be evaluated for those specific constraints.

Part Context

This part belongs to ROHM's line of motor and motion controllers, specifically optimized for consumer electronics. It is part of the BD654xx series, which focuses on integrating H-bridge drivers with low power dissipation. The E2 suffix typically denotes environmental compliance updates. It serves as a specialized driver for small motors rather than general-purpose power switching, distinguishing it from higher-voltage industrial counterparts.

Replacement Considerations

The BD65494MUV is listed as an alias for this part number. No other direct cross-references are confirmed in public documentation. Verify pin compatibility and thermal characteristics before substituting with similar H-bridge drivers from other manufacturers.
