DRV8833RTYT

Overview

The DRV8833RTYT is a dual H-bridge motor driver manufactured by Texas Instruments, designed for low-voltage bipolar stepper and single/dual DC motor applications. It operates within a supply voltage range of 2.7 V to 10.8 V and delivers an output current of up to 1.5 A per channel. The device features a WQFN-16 surface-mount package suitable for space-constrained designs. It supports a wide operating temperature range from -40°C to +85°C and includes built-in protection mechanisms such as over-current shutdown and thermal shutdown. The quiescent supply current is typically 1.7 mA, ensuring efficient power management in battery-operated systems.

Feature Summary

• Dual half-bridge architecture supporting independent control of two motors or one bipolar stepper motor
• Integrated over-current and thermal protection circuits for enhanced system reliability
• Low quiescent current consumption optimized for portable and battery-powered applications

Applications

• Bipolar stepper motor control in consumer electronics
• DC motor drive for small appliances and robotics
• Vibration motor drivers in handheld devices

Procurement Notes

Verify the specific suffix RTYT against official Texas Instruments documentation to confirm pinout compatibility and tape-and-reel specifications. Ensure that the procurement source provides valid RoHS compliance data and moisture sensitivity level information. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm that the ordering quantity aligns with standard reel sizes if bulk purchasing is required.

Selection Notes

Select the DRV8833RTYT when a compact dual H-bridge solution is needed for low-voltage motor control. This component is appropriate for applications requiring independent channel control without external logic. Consider the WQFN-16 package size for PCB layout constraints. Evaluate the 1.5 A continuous current rating against peak load requirements to ensure adequate headroom. Compare thermal performance characteristics against the expected ambient operating conditions.

Part Context

The DRV8833 series comprises dual H-bridge motor drivers intended for various motion control tasks. The RTYT variant specifically denotes the WQFN-16 package configuration with reel packaging. This part belongs to the broader family of Texas Instruments motor drivers, which share common architectural features but differ in package types and current ratings. The series is designed to simplify motor interface design by integrating necessary control logic and protection features into a single IC.

Replacement Considerations

The DRV8833RTYRG4 is a documented equivalent variant within the same product family. Verify pin-to-pin compatibility and electrical parameter alignment before substitution. Ensure that any replacement part meets the same environmental and regulatory standards required for the original design.
