DRV8244HQRYJRQ1

Overview

The DRV8244HQRYJRQ1 is an automotive-grade H-bridge driver designed for high-power applications. It features a maximum output current of 21 A and supports a supply voltage range from 4.5 V to 35 V, with absolute maximum ratings up to 40 V. The device utilizes a BiCMOS process and offers low on-resistance in the VQFN-HR package. It integrates N-channel H-bridges, charge pump regulators, and high-side current detection. Key electrical parameters include PWM operation up to 25 kHz and a typical standby current of 1 μA at +25°C.

Feature Summary

• Integrated current detection and proportional load current output via IPROPI pin without external shunt resistors
• Configurable control modes supporting single full-bridge or two independent half-bridge configurations
• Comprehensive protection mechanisms including overcurrent, overtemperature, and power supply voltage monitoring
• Advanced EMI management through configurable slew rates and spread-spectrum clocking capabilities

Applications

• Automotive brushed DC motors and solenoids
• Door modules, wiper modules, trunk, and seat actuators
• Body control modules (BCM) and steering systems
• Gasoline engine systems and onboard chargers

Procurement Notes

Verify the specific suffix HQRYJRQ1 against official Texas Instruments documentation to confirm package type, temperature grade, and interface variant. Ensure compliance with AEC-Q100 Grade 1 requirements for your target application environment. Cross-reference the datasheet revision history for any updates to functional safety documentation or recommended operating conditions prior to final design integration.

Selection Notes

Select this component when high current capacity up to 21 A is required for automotive motor control. The integrated current sensing eliminates the need for external shunt resistors, reducing bill of materials cost. Consider the available interface variants, such as SPI or hardwired options, based on system complexity and diagnostic needs. The robust thermal performance and compact packaging make it suitable for space-constrained automotive environments.

Part Context

This part belongs to the DRV8244-Q1 family of automotive H-bridge drivers from Texas Instruments. The family is designed for scalable power solutions, allowing designers to use pin-compatible packages with different current ratings. The DRV8244 specifically targets high-load applications requiring precise current control and advanced diagnostic features within a single monolithic device.

Replacement Considerations

Consult the official Texas Instruments product selection guide for verified pin-to-pin compatible alternatives within the DRV824x series. Substitutes may vary in current rating, package dimensions, or interface protocols. Do not assume interchangeability with non-automotive grade parts or devices from other manufacturers without rigorous validation.
