Overview
The DRV8871DDA is a brushed DC motor driver from Texas Instruments, housed in an 8-SO PowerPAD package. It features an H-bridge configuration with four N-channel MOSFETs, supporting a supply voltage range of 6.5 V to 45 V and delivering up to 3.6 A peak current. The device integrates current sensing and regulation, utilizing PWM for speed control. It operates within a temperature range of -40°C to +125°C and includes protection against under-voltage lockout, overcurrent, and thermal shutdown.
Feature Summary
- Integrates advanced current regulation circuitry without requiring external sense resistors or analog voltage references.
- Provides comprehensive fault protection including under-voltage lockout, overcurrent protection, and thermal shutdown with automatic recovery.
- Supports bidirectional motor control via two logic inputs and enters low-power sleep mode when both inputs are low.
Applications
- Printers
- Appliances
- Industrial equipment
- Small machinery
Procurement Notes
Verify the specific suffix 'DDA' against the official datasheet to confirm tube packaging versus 'DDAR' tape-and-reel options. Ensure the design accommodates the SO-PowerPad-8 thermal requirements for the specified operating conditions. Confirm RoHS compliance status for the specific manufacturing batch prior to integration.
Selection Notes
Select this component for applications requiring integrated current limiting to reduce system power demands and eliminate large stabilization capacitors. It is suitable for designs needing robust fault protection and automatic recovery without complex external sensing circuits. Consider the thermal performance of the PowerPAD package for high-current continuous operation scenarios.
Part Context
This part belongs to the DRV887x family of single H-bridge motor drivers. It shares functional similarities with the DRV8870 but offers specific integration levels for current sensing. The 'DDA' designation indicates a tube package variant, distinct from the reel-packaged 'DDAR' version, while maintaining identical electrical characteristics and pinout compatibility within the series.
Replacement Considerations
The DRV8871DDAR is a direct pin-compatible alternative differing only in packaging format (tape and reel vs. tube). Verify if the application requires specific automotive qualification, in which case the DRV8871DDARQ1 may be appropriate.
