Overview
The DRV8143PQDGQRQ1 is an automotive-grade half-bridge driver manufactured by Texas Instruments. It supports a supply voltage range of 4.5 V to 40 V and delivers a continuous output current of 20 A. The device operates within a temperature range of -40°C to +125°C and utilizes a 28-pin HVSSOP package. It features a PWM frequency capability of 125 kHz and a quiescent current of 10 mA. This component is designed for high-reliability motor control applications in automotive environments.
Feature Summary
- Integrated current sensing and feedback mechanism for precise load monitoring
- Automotive qualification compliant with AEC-Q100 standards for durability
- Supports high-frequency PWM operation up to 125 kHz for efficient motor control
Applications
- Automotive window lift motors
- Seat adjustment actuators
- HVAC blower fan control systems
Procurement Notes
Verify the complete part number including the PQDGQ suffix to ensure correct packaging and automotive grade specification. Confirm that the intended application requires the specific 20 A current rating and 40 V maximum voltage limit. Check datasheet thermal guidelines for the HVSSOP-28 package to ensure adequate heat dissipation design. Validate compatibility with the system's logic voltage levels and PWM signal requirements before integration.
Selection Notes
Select this component when a single half-bridge configuration with integrated current sensing is required for automotive loads. It is suitable for applications needing 20 A continuous drive capability within a compact 28-pin package. Consider alternative packages like VQFN if higher power density or different pinout compatibility is needed, such as with the DRV8143HQRXYRQ1 variant.
Part Context
This device belongs to the DRV8143 family of automotive half-bridge drivers from Texas Instruments. The family includes variants with different packages and current ratings, such as the DRV8143HQRXYRQ1 which offers similar electrical performance in a VQFN-14 package. These components are designed to replace older discrete solutions or simpler drivers in modern automotive body electronics.
Replacement Considerations
The DRV8143HQRXYRQ1 serves as a functional substitute with identical electrical specifications but utilizes a VQFN-14 package instead of HVSSOP-28. Designers must account for footprint differences and potential thermal management adjustments when swapping between these package types.
