DRV8803DWR

Overview

The DRV8803DWR is a four-channel low-side driver manufactured by Texas Instruments, housed in a 20-pin SOIC package. It features an integrated power MOSFET architecture with a wide operating supply voltage range of 8.2V to 60V. The device supports a maximum output current of 1.5A per channel when conducting individually, or 800mA across all four channels simultaneously at 25°C. It operates within a junction temperature range of -40°C to +150°C and includes built-in protection mechanisms such as overcurrent detection with a response time of less than 1μs.

Feature Summary

• Integrates four independent low-side NMOS FET drivers with clamping diodes for efficient switching of inductive loads.
• Provides comprehensive protection including overcurrent detection with fast fault indication via the nFAULT pin.
• Supports PWM control frequencies up to 100kHz for precise motor speed regulation and lighting dimming applications.

Applications

• Industrial control systems requiring relay and solenoid driving for PLC and DCS modules
• Automotive electronics for window lifters and door lock actuators
• Consumer appliances utilizing stepper motors in printers and scanners

Procurement Notes

Verify the specific suffix 'DWR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the thermal management design accommodates the SOIC-20 package limitations under continuous load conditions. Ensure compatibility with the system's logic voltage levels for the parallel interface inputs before finalizing procurement specifications.

Selection Notes

Select this component when designing circuits that require simultaneous control of multiple low-side inductive loads within a single integrated solution. It is suitable for applications demanding high voltage tolerance up to 60V and robust fault protection capabilities. Consider the thermal dissipation requirements of the SOIC-20 package when determining the number of active channels for sustained operation.

Part Context

This part belongs to the DRV8803 family of motor and motion controllers from Texas Instruments. It serves as a dedicated driver for unipolar stepper motors and general-purpose inductive loads. The device simplifies circuit design by integrating power switches and protection logic, reducing the external component count compared to discrete solutions.

Replacement Considerations

The DRV8803DW is a tube-packaged variant of the same functional device. Verify if the change in packaging format affects the manufacturing process without altering electrical performance.
