Overview
The DRV8841PWP is a dual H-bridge motor driver IC manufactured by Texas Instruments, housed in a 28-pin HTSSOP package. It operates within a supply voltage range of 8.2 V to 45 V and delivers an output current of 1.75 A per channel. The device supports bipolar stepper motors and DC brushed motors, featuring a typical switching frequency of 50 kHz. It functions reliably across an operating temperature range from -40 °C to +85 °C, with a junction temperature capability up to 150 °C.
Feature Summary
- Integrates two independent H-bridge drivers for simultaneous control of multiple loads
- Includes internal protection mechanisms against overcurrent, short circuits, undervoltage lockout, and overtemperature conditions
- Utilizes power MOSFET technology for efficient drive performance
Applications
- Bipolar stepper motor control systems
- DC brushed motor actuation
- Printers and scanners
- Office automation equipment
Procurement Notes
Verify the specific suffix 'PWP' confirms the tube packaging format rather than tape-and-reel delivery. Confirm RoHS compliance status and REACH SVHC declarations match current regulatory requirements. Ensure the ordering part number aligns with the required thermal performance specifications for the intended application environment.
Selection Notes
Select this component when dual-channel motor control is required within a compact surface-mount footprint. The 1.75 A current rating suits moderate-load applications without extensive external heatsinking. Consider the 28-pin HTSSOP package for PCB space constraints while ensuring adequate thermal management strategies are implemented for sustained operation.
Part Context
This device belongs to the DRV88xx family of Europa Motor Drivers designed for automated equipment. It complements other variants like the DRV8840 and DRV8842, offering a balanced solution for integrated motor control. The HTSSOP package provides thermal enhancement suitable for dense electronic assemblies in consumer and industrial machinery.
Replacement Considerations
The DRV8840PWP serves as a related alternative within the same product family, though it features a half-bridge configuration instead of dual H-bridges. Verify pin compatibility and current ratings before substitution.
