DRV8411RTER

Overview

The DRV8411RTER is a dual H-bridge motor driver manufactured by Texas Instruments, designed for driving bipolar stepper motors, brushed DC motors, solenoids, and other inductive loads. It features a wide supply voltage range of 1.65 V to 11 V and delivers a peak output current of 4 A per bridge. The device integrates a triple charge pump architecture to enable operation at low voltages and supports 100% duty cycle running. It utilizes a PWM control interface compatible with 1.8 V, 3.3 V, and 5 V logic levels.

Feature Summary

• Integrates a triple charge pump architecture to support operation down to 1.65 V and enable 100% duty cycle performance.
• Provides integrated current regulation by comparing internal reference voltage with external sense resistor voltage to limit startup and stall currents.
• Includes comprehensive protection mechanisms such as under-voltage lockout, automatic retry over-current protection, thermal shutdown, and a fault indication pin.

Applications

• Driving bipolar stepper motors
• Controlling one or two brushed DC motors
• Actuating solenoids and other inductive loads

Procurement Notes

Verify the specific suffix RTER corresponds to the 16-WQFN (3x3) package and tape-and-reel shipping configuration. Confirm that the order quantity aligns with the manufacturer's standard packaging requirements. Ensure compatibility with the target system's voltage levels and thermal management capabilities before finalizing procurement.

Selection Notes

Select this component when a compact dual H-bridge solution is required for low-voltage applications starting at 1.65 V. It is suitable for designs needing integrated current limiting and protection without external discrete components. Consider the 16-WQFN package size constraints and verify that the 4 A peak current rating meets the load requirements.

Part Context

The DRV8411 belongs to Texas Instruments' portfolio of dual half-bridge motor drivers. It offers pin-to-pin compatibility with related devices such as the DRV8833, DRV8847, and DRV8410, allowing for design scalability. The RTER suffix indicates the specific reel-based packaging format used for surface-mount assembly.

Replacement Considerations

Pin-compatible alternatives include DRV8833, DRV8833C, DRV8847, DRV8410, and DRV8411A. Verify that the substitute part meets the required on-resistance and current handling specifications for the specific application load.
