Overview
The DRV8843PWPR is a dual H-bridge motor driver manufactured by Texas Instruments, designed for controlling bipolar stepper motors and brushed DC motors. It operates within a supply voltage range of 8.2 V to 45 V and delivers an output current of 2.5 A per channel. The device integrates power MOSFETs in a half-bridge configuration with four outputs. It functions within an ambient temperature range of -40°C to +85°C and supports junction temperatures up to 150°C. The component is housed in a 28-pin HTSSOP package and features a typical operating supply current of 5 mA.
Feature Summary
- Integrates dual H-bridge architecture with fully integrated control and power stages for simplified system design.
- Supports PWM current control to manage motor torque and reduce heat dissipation during operation.
- Includes built-in protection mechanisms against overcurrent, under-voltage lockout, and thermal shutdown.
Applications
- Bipolar stepper motor control systems
- Brushed DC motor drives
- Home appliance motor control
- Industrial automation actuators
Procurement Notes
Verify the specific suffix 'PWPR' corresponds to the HTSSOP-28 package and tape-and-reel packaging format. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the ordering part number matches the exact electrical specifications required for your application circuit design.
Selection Notes
Select this component when a dual H-bridge solution is needed for driving two brushed DC motors or one bipolar stepper motor. It is suitable for applications requiring a wide input voltage range up to 45 V. Consider the thermal performance and PCB layout requirements associated with the HTSSOP-28 package for adequate heat dissipation.
Part Context
This part belongs to the DRV88xx family of Europa Motor Drivers from Texas Instruments. It is functionally similar to the DRV8841 but offers higher current capability. The DRV8843EVM evaluation module was previously available for development purposes but has been discontinued.
Replacement Considerations
The DRV8841PWPR is a documented substitute within the same product family. Verify pin compatibility and current ratings before implementation.
