Overview
The DRV8424ERGER is a bipolar stepper motor driver from Texas Instruments, part of the DRV8424E series. It features an integrated half-bridge architecture capable of delivering up to 2.5 A output current per phase. The device supports a STEP/DIR interface and includes smart tune technology for optimized performance. It operates within a supply voltage range of 4.5 V to 33 V and functions across a temperature range of -40°C to +125°C. Packaged in a VQFN-24 format for surface mount installation, it integrates current sense capabilities.
Feature Summary
- Integrates smart tune technology for automatic optimization of stepper motor drive parameters
- Supports high-resolution microstepping up to 1/256 step resolution
- Features built-in current sensing for precise torque control and protection
Applications
- Bipolar stepper motor control systems
- Dual brushed DC motor driving applications
- Industrial automation motion control modules
Procurement Notes
Verify the specific suffix 'RGER' against the official Texas Instruments datasheet to confirm package type and reel specifications. Ensure compatibility with the target PCB footprint for the VQFN-24 package. Cross-reference the maximum supply voltage rating of 33 V with the system power design to prevent overvoltage damage during procurement validation.
Selection Notes
Select this component when a compact solution for bipolar stepper motors is required with integrated current sensing. It is suitable for designs needing high microstepping resolution and automatic tuning capabilities. Compare against the DRV8425E series if higher current capacity or different voltage ratings are necessary for the specific application requirements.
Part Context
This part belongs to the DRV8424E family of dual H-bridge motor drivers. It shares architectural similarities with the DRV8425E but differs in maximum voltage and current ratings. The family is designed for applications requiring efficient stepper motor control with minimal external components, integrating logic and power stages into a single small form factor.
Replacement Considerations
The DRV8424EPWPR is a pin-compatible alternative within the same family offering the same functional specifications in a different package variant.
