DRV8452PWPR

Overview

The DRV8452PWPR is a high-performance stepper motor driver from Texas Instruments, designed for applications requiring precise motion control. It operates on a wide supply voltage range of 4.5 V to 55 V and supports standard 24 V and 36 V power rails. The device integrates MOSFETs with a low on-resistance of 100 mΩ (HS + LS) at 24 V and 25°C. In the PWP package, it delivers a full-scale current capacity of 4 A and an RMS current of 2.8 A. It features an integrated indexer supporting up to 1/256 microstepping, automatic torque control, and silent step technology for noise reduction.

Feature Summary

• Integrates a programmable microstep indexer supporting resolutions up to 1/256 microstep
• Features automatic torque control that adjusts current based on load requirements to improve efficiency
• Includes silent step decay mode to ensure quiet operation during stationary and low-speed conditions
• Provides sensorless stall detection capability to eliminate the need for mechanical end stops

Applications

• High-precision industrial automation systems
• Medical equipment requiring quiet motor operation
• Office automation devices such as printers and scanners
• Security systems including access control mechanisms

Procurement Notes

Verify the specific suffix PWPR corresponds to the tape-and-reel packaging configuration required for your assembly process. Confirm that the thermal performance of the PWP package meets the thermal dissipation requirements of your application design. Ensure compatibility with the logic input voltage levels supported by the controller interface.

Selection Notes

Select this component when a wide input voltage range up to 55 V is required alongside high current drive capabilities in a compact form factor. Consider the PWP package variant if the application demands a full-scale current of 4 A. Evaluate the integrated protection features, such as over-current and thermal shutdown, to simplify system safety design without external components.

Part Context

This part belongs to the DRV845x family of stepper motor drivers, which are designed for high-power density applications. The family includes pin-compatible variants like the DRV8462 and DRV8461, offering higher voltage ratings and current capacities. The DRV8452 specifically targets applications needing robust performance with integrated intelligence features like automatic tuning and microstepping interpolation.

Replacement Considerations

The DRV8452DDWR is a pin-compatible alternative within the same family that offers higher current ratings of 5 A full-scale and 3.5 A RMS. Other compatible options include the DRV8462 and DRV8461 for applications requiring higher voltage tolerance up to 65 V.
