DRV8847PWR

Overview

The DRV8847PWR is a dual H-bridge motor driver integrated circuit designed for low-voltage applications. It features an integrated charge pump to drive high-side N-channel power MOSFETs, enabling efficient operation with supply voltages ranging from 2.7V to 13.5V. The device supports continuous output currents of up to 1.5A per channel with peak currents reaching 2.5A. It includes built-in protections such as overcurrent protection, thermal shutdown, and under-voltage lockout. The PWR package provides a compact solution suitable for space-constrained designs.

Feature Summary

• Integrated charge pump facilitates high-side N-channel MOSFET driving for improved efficiency
• Comprehensive protection mechanisms including overcurrent, thermal shutdown, and undervoltage lockout
• Supports multiple control modes including PWM, direction, and enable functions

Applications

• Home appliances requiring dual motor control
• Industrial automation systems with low-voltage DC motors
• Office equipment such as printers and scanners

Procurement Notes

Verify the specific suffix (PWR) indicates the TSSOP-16 package and tape-and-reel packaging when ordering. Confirm that the operating temperature range meets your environmental requirements. Ensure input voltage levels remain within the specified 2.7V to 13.5V range to prevent damage. Check for any regional compliance certifications required for your final product integration.

Selection Notes

Choose this component when a dual H-bridge solution is needed for low-voltage DC motors. It is suitable for applications requiring moderate current levels without external heat sinks. Consider alternative parts if higher current capacity or different voltage ranges are necessary. Evaluate board space constraints as the TSSOP-16 package offers a compact footprint.

Part Context

The DRV8847 belongs to Texas Instruments' family of dual H-bridge motor drivers. It complements other devices like the DRV8848 and DRV8849, which offer variations in current ratings and features. This series is commonly used in consumer electronics and industrial controls where reliable motor management is essential.

Replacement Considerations

Direct substitutes include the DRV8848PW and DRV8849PW, which offer similar functionality with potentially different current capabilities. Verify pin compatibility and electrical specifications before swapping components to ensure system integrity.
