DRV8244PQDGQRQ1

Overview

The DRV8244PQDGQRQ1 is an automotive-grade H-bridge driver from Texas Instruments, designed for brushed DC motor and solenoid applications. It features a maximum output current of 21 A and operates within a supply voltage range of 4.5 V to 35 V, with absolute maximum ratings up to 40 V. The device utilizes a HVSSOP-28 surface-mount package and supports PWM frequencies up to 25 kHz. It includes integrated N-channel H-bridges, charge pump regulators, high-side current detection, and protection circuits such as overcurrent and overtemperature safeguards.

Feature Summary

• Configurable as a single full-bridge or two independent half-bridges for flexible load control
• Integrated high-side current sensing with proportional output on the IPROPI pin
• Supports configurable fault reactions including lockout or retry modes
• Features low quiescent current in shutdown mode for energy efficiency

Applications

• Automotive door modules
• Wiper systems
• Trunk and seat adjustment actuators
• Body control modules (BCM)
• Steering systems

Procurement Notes

Verify that the specific suffix PQDGQRQ1 corresponds to the HVSSOP-28 package variant with the specified electrical characteristics. Confirm AEC-Q100 Grade 1 qualification status for your target temperature range. Ensure compatibility with the SPI interface variant if digital configuration is required, as hardware variants differ in logic power sourcing and diagnostic capabilities.

Selection Notes

Select this component when a robust automotive H-bridge driver with integrated current sensing is required. It is suitable for applications needing 21 A continuous current capability in a compact form factor. Consider the SPI interface for advanced diagnostic monitoring and programmable fault responses compared to hardwired alternatives. Ensure thermal management aligns with the HVSSOP-28 package's dissipation limits under expected load conditions.

Part Context

This part belongs to the DRV8244-Q1 family of automotive H-bridge drivers. It shares functional similarities with other members like DRV8244SQPWPRQ1 but differs in packaging and interface options. The family is designed for scalable R_ON performance and includes variants with HW, SPI(P), and SPI(S) interfaces to support different system architectures and diagnostic requirements.

Replacement Considerations

Direct substitutes include other DRV8244-Q1 variants such as DRV8244SQPWPRQ1 or DRV8244HQRYJRQ1, provided the package type and interface specifications match the design requirements. Verify that any replacement maintains the same AEC-Q100 qualification and electrical ratings.
