DRV8803DYZR

Overview

The DRV8803DYZR is a low-side driver manufactured by Texas Instruments, designed for motor and motion control applications. It features four independent output channels capable of delivering up to 1.9 A continuous output current per channel. The device operates within a supply voltage range of 8.2 V to 60 V and maintains a low quiescent supply current of 1.6 mA. It supports an extended operating temperature range from -40°C to +125°C. The component is housed in a SOT-23-16 surface-mount package, suitable for space-constrained designs requiring reliable low-side switching capabilities.

Feature Summary

• Integrates four independent low-side driver channels for multi-motor or solenoid control
• Supports high-voltage operation with a wide input supply range up to 60 V
• Provides robust thermal protection mechanisms to ensure stable performance under load
• Features low quiescent current consumption to minimize power loss in standby modes

Applications

• Brushed DC motor control systems
• Unipolar stepper motor drivers
• Solenoid actuation circuits
• Ignition system controllers
• General-purpose low-side switching loads

Procurement Notes

Verify the specific suffix DYZR against the manufacturer's official datasheet to confirm the exact tape-and-reel packaging configuration and pinout compatibility. Ensure that the procurement source provides valid RoHS compliance documentation as required for environmental regulations. Cross-reference the part number with the latest Texas Instruments product selection guide to confirm availability status and any potential obsolescence notices before finalizing orders.

Selection Notes

Select this component when designing circuits requiring multiple independent low-side switches within a compact SOT-23-16 footprint. It is appropriate for applications demanding a maximum supply voltage of 60 V and individual channel currents up to 1.9 A. Consider the thermal dissipation requirements associated with the small package size when determining heat sink needs or PCB copper area allocation for optimal thermal performance across the specified temperature range.

Part Context

This device belongs to the DRV8803 series of integrated motor drivers from Texas Instruments. The series is engineered to simplify the design of motor control systems by combining control logic and power stages. The DRV8803DYZR variant specifically utilizes the SOT-23-16 package, distinguishing it from other variants like the DRV8803DWR which uses a SOIC-20 package. This family targets cost-sensitive and space-constrained industrial and consumer applications.

Replacement Considerations

The DRV8803DWR is a functional equivalent within the same series but utilizes a different SOIC-20 package. Designers must verify pin-to-pin compatibility and thermal characteristics when substituting between these package variants. No other direct cross-model replacements are confirmed in the provided documentation.
