DRV8803DW

Overview

The DRV8803DW is a quad low-side driver integrated circuit manufactured by Texas Instruments, designed for driving unipolar solenoids and relays. It features four independent output channels capable of delivering up to 1.5 A per channel. The device operates within a supply voltage range of 8.2 V to 60 V and supports an extended operating temperature range from -40°C to +125°C. With a quiescent supply current of 1.6 mA, it offers efficient power management. The component is housed in a 20-pin SOIC package (SOIC-20) suitable for surface-mount assembly.

Feature Summary

• Integrates four independent low-side driver outputs for simultaneous control of multiple loads
• Supports high-current switching with individual channel capability up to 1.5 A
• Operates reliably across an extended industrial temperature range up to +125°C
• Features low quiescent current consumption for improved system efficiency

Applications

• Unipolar solenoid actuation systems
• Relay driver circuits
• Industrial motion control interfaces
• Automotive ignition and lighting modules

Procurement Notes

Verify the specific ordering suffix and package variant against the official Texas Instruments datasheet before procurement. Confirm that the SOIC-20 tube packaging aligns with assembly requirements. Check for end-of-life status or obsolescence notices, as availability may be limited. Ensure compatibility with existing board layouts and thermal management strategies for the 20-pin form factor.

Selection Notes

Select this component when a quad low-side driver is required for unipolar loads such as solenoids or relays. It is suitable for applications needing individual channel control without serial interface complexity. Consider the 60 V maximum rating and 1.5 A per-channel limit for load matching. The SOIC-20 package is appropriate for standard surface-mount manufacturing processes requiring robust thermal performance.

Part Context

The DRV8803DW belongs to the DRV8803 series of quad low-side drivers from Texas Instruments. It is distinct from the DRV8804 and DRV8806 series, which incorporate serial interface capabilities. This model provides direct logic input control for each channel, simplifying design for basic switching applications. It serves as a dedicated solution for multi-channel actuator control in automotive and industrial environments.

Replacement Considerations

The DRV8803DWR is a pin-compatible alternative offering the same functional specifications but in tape-and-reel packaging instead of tubes. Other family members like the DRV8804 or DRV8806 provide similar driver counts but include additional serial interface features not present in the DRV8803DW.
