Overview
The DRV8436EPWPR is a bipolar stepper motor driver from Texas Instruments, designed for industrial applications. It operates within a supply voltage range of 4.5 V to 48 V and delivers an output current of 1.5 A. The device features a half-bridge topology with two outputs and supports PWM interfaces. It functions at a working frequency of 400 kHz with a quiescent supply current of 5 mA. The component is housed in a 28-pin HTSSOP package and withstands operating temperatures from -40°C to +125°C.
Feature Summary
- Integrated open load detection capability for diagnostic monitoring
- Automotive-grade qualification supporting harsh industrial environments
- Full integration of control logic and power MOSFET stages
Applications
- Industrial automation systems requiring robust motor control
- Automotive electronic components subject to strict reliability standards
- General-purpose motion control circuits utilizing bipolar stepper motors
Procurement Notes
Verify the specific suffix 'EP' indicates automotive grade qualification distinct from standard variants. Confirm the HTSSOP-28 package dimensions match your PCB footprint requirements. Ensure compatibility with the 4.5 V to 48 V input range for your target system design.
Selection Notes
Select this model when automotive reliability and open load diagnostics are required. Compare against the DRV8436RGER if automotive qualification is unnecessary but a smaller VQFN package is preferred. Evaluate thermal performance within the specified temperature range for your enclosure constraints.
Part Context
This part belongs to the DRV8436 family of integrated stepper drivers. It shares core electrical specifications with other variants but differs in packaging and qualification level. The EP suffix specifically denotes enhanced performance or automotive compliance compared to standard commercial versions.
Replacement Considerations
The DRV8436ERGER is listed as a parameter-equivalent substitute. Verify package compatibility between HTSSOP-28 and alternative options before substitution.
