Overview
The DRV8833LRTYR is a fully integrated dual H-bridge motor driver manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 10.8 V and supports bipolar stepper motors or two DC motors. The device features a Power MOSFET technology with PWM control interface. Key electrical parameters include an output current capability of 1.5 A, a quiescent supply current of 1.7 mA, and an operating temperature range from -40°C to +85°C. It is housed in a WQFN-16 package.
Feature Summary
- Fully integrated control and power stage for simplified design
- Supports operation with bipolar stepper motors or dual DC motors
- Includes current regulation capabilities for precise motor control
Applications
- Toy mechanisms
- Printer drive systems
- General mechatronic applications
Procurement Notes
Verify the specific suffix 'L' against the official Texas Instruments datasheet to confirm it denotes a valid production variant distinct from standard DRV8833 models. Ensure the component matches the WQFN-16 package dimensions and humidity sensitivity classifications listed in the manufacturer's documentation before integration into the bill of materials.
Selection Notes
Select this component when a compact solution for driving bipolar stepper or dual DC motors is required within low-voltage constraints. The integrated nature reduces external component count. Verify that the 1.5 A output current meets the load requirements and that the WQFN-16 package fits the available PCB real estate.
Part Context
This part belongs to the DRV8833 family of dual H-bridge motor drivers from Texas Instruments. It shares core functionality with variants like the DRV8833RTYR but may differ in specific manufacturing lot codes or minor parameter tolerances defined by the manufacturer. It serves as a PMIC subcategory component for motion control.
Replacement Considerations
The DRV8833RTYR is a documented alternative within the same product family. Confirm pinout compatibility and verify if the 'L' suffix implies any functional differences compared to the standard RTYR variant before substitution.
