Overview
The DRV8436PWPR is a bipolar stepper motor driver from Texas Instruments, housed in an HTSSOP-28 package. It supports a supply voltage range of 4.8 V to 48 V and delivers up to 1.5 A output current per channel. The device operates within a temperature range of -40°C to +125°C and features a quiescent supply current of 5 mA.
Feature Summary
- Integrates half-bridge power stages for bipolar stepper motor control
- Supports PWM interface for step and direction inputs
- Includes thermal shutdown protection for system reliability
Applications
- Bipolar stepper motor drives
- Industrial automation systems
- General-purpose motion control applications
Procurement Notes
Verify the specific suffix PWPR corresponds to the HTSSOP-28 package and reel/cut-tape availability. Confirm RoHS compliance status through official documentation. Check for any Product Change Notifications (PCN) dated June 14, 2024, regarding potential manufacturing updates or material changes before finalizing procurement.
Selection Notes
Select this component when a 48-V rated, 1.5-A bipolar stepper driver is required in an HTSSOP-28 surface-mount package. Ensure the application voltage stays within the 4.8 V to 48 V range. Consider the 5 mA quiescent current for power-sensitive designs. Verify that the thermal performance of the HTSSOP-28 package meets the heat dissipation requirements for the expected load current.
Part Context
This part belongs to the DRV8436 series of stepper motor drivers from Texas Instruments. It shares core electrical specifications with variants like the DRV8436RGER, differing primarily in the physical package type. The series is designed for industrial and general-purpose motion control applications requiring integrated power MOSFETs.
Replacement Considerations
The DRV8436EPWPR is a parameter-equivalent alternative within the same family. Both share the HTSSOP-28 package and similar electrical characteristics. Verify pinout compatibility and specific feature differences between the standard and E-series variants before substitution.
