DRV88471RTER

Overview

The DRV88471RTER is a dual H-bridge motor driver from Texas Instruments, designed for industrial and mechatronic applications. It operates with a supply voltage range of 2.7 V to 18 V and delivers an output current of 2 A per bridge. The device features a 400 kHz PWM frequency and includes a 5 V regulator. It is housed in a WQFN-16 package (3x3 mm) and supports operation temperatures from -40°C to +125°C.

Feature Summary

• Dual H-bridge architecture for independent motor control
• Integrated 5 V regulator for logic power
• Wide operating temperature range for harsh environments

Applications

• Industrial automation systems
• Home appliance motor control
• Electronic point-of-sale (ePOS) printers
• Mechatronic devices

Procurement Notes

Verify the exact part number suffix against official Texas Instruments documentation to ensure correct packaging and tape/reel specifications. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as these details are subject to change and vary by region.

Selection Notes

Select this component when a compact dual H-bridge solution is required for low-voltage DC motors. Ensure the thermal design accommodates the WQFN-16 package constraints. Verify that the 2 A continuous current rating meets the load requirements under the expected ambient temperature conditions.

Part Context

This device belongs to the DRV8847 family of motor drivers. It shares core functional characteristics with other variants in the series but differs in specific packaging options such as the WQFN-16 form factor. The family is targeted at cost-sensitive, space-constrained applications requiring reliable dual-channel drive capabilities.

Replacement Considerations

Check for pin-compatible alternatives within the same family, such as DRV8847RTET or DRV8847SPWR, ensuring package dimensions and electrical ratings match the original design requirements.
