BD65492MUV-E2

Overview

The BD65492MUV-E2 is a dual H-bridge motor driver manufactured by ROHM Semiconductor, designed for high-speed switching applications. It features a VQFN-24 package with dimensions of 4.0x4.0 mm and a thickness of 1.0 mm. The device supports a load voltage range of 1.8 V to 16 V and operates on a supply voltage between 2.5 V and 5.5 V. It delivers a maximum DC output current of 1 A per channel with a typical output on-resistance of 0.9 Ω. The operating temperature range spans from -30°C to +85°C, and the junction temperature can reach up to 150°C.

Feature Summary

• Dual H-bridge configuration enabling independent control of two brushed DC motors or one stepper motor coil pair.
• High-speed switching capability with turn-on time of 200 ns and turn-off time of 80 ns for efficient operation.
• Charge-pump-less design utilizing P-channel DMOS for the upper side transistors to simplify circuit requirements.
• Integrated protection circuits including Under Voltage Lock Out (UVLO) and Thermal Shutdown to ensure reliability.

Applications

• Mobile devices requiring low-power motor actuation
• Home appliance fan and pump control systems
• Portable electronic equipment with vibration or linear motor drivers

Procurement Notes

Verify the specific suffix E2 indicates RoHS compliance and lead-free status as per manufacturer documentation. Confirm the VQFN-24 package variant matches the required PCB footprint. Ensure input voltage levels remain within the 2.5 V to 5.5 V range for logic and 1.8 V to 16 V for loads to prevent damage. Check thermal dissipation requirements given the small surface mount package size.

Selection Notes

Select this component when dual-channel H-bridge control is needed in a compact form factor. It is suitable for applications requiring fast response times and low standby current. Consider the 1 A continuous current limit and 0.9 Ω on-resistance for power loss calculations. Ensure the application environment stays within the specified -30°C to +85°C operating temperature range.

Part Context

This part belongs to the BD65492MUV series of high-speed H-bridge drivers from ROHM. It is categorized under Brushed DC Motor Drivers and PMIC solutions. The series is designed for mobile and home appliance markets, offering a balance of performance and power efficiency in a small outline package.

Replacement Considerations

Check for BD65491FV if only single-channel H-bridge functionality is required. Verify compatibility with BD65494MUV for single-channel applications with similar voltage ranges but different packaging. Cross-reference pinouts and electrical characteristics before substitution.
