Overview
The DRV8848PWP is a dual H-bridge motor driver manufactured by Texas Instruments, designed for driving brushed DC motors and stepper motors. It operates within a supply voltage range of 2.7 V to 18 V and supports continuous output currents up to 1.5 A per bridge with peak currents reaching 3 A. The device integrates power MOSFETs in an HTSSOP-16 package (PWPR variant available). Key features include overcurrent protection, thermal shutdown, and low standby current. It is suitable for applications requiring compact motor control solutions.
Feature Summary
- Integrates two independent H-bridge drivers capable of driving brushed DC motors or bipolar stepper motors
- Includes built-in protections such as overcurrent protection and thermal shutdown for enhanced reliability
- Features low standby current consumption to support battery-powered applications
- Supports PWM speeds up to 100 kHz for precise motor speed control
Applications
- Home appliances including washing machines and vacuum cleaners
- Office automation equipment such as printers and scanners
- Industrial automation systems requiring compact motor control
- Battery-powered tools and portable devices
Procurement Notes
Verify the exact part number suffix to confirm packaging type; PWP indicates tube packaging while PWPR indicates reel packaging. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure proper ESD handling procedures are followed during storage and assembly due to the sensitivity of the integrated circuit components.
Selection Notes
Select this component when a dual H-bridge configuration is required for driving two brushed DC motors or one bipolar stepper motor. Consider the 1.5 A continuous current rating and 18 V maximum supply voltage limits. Evaluate thermal management requirements based on expected load conditions and ambient temperature. Compare against single H-bridge alternatives if only one motor channel is needed to optimize board space and cost.
Part Context
The DRV8848 belongs to Texas Instruments' DRV88xx series of motor drivers, which are designed for various motor control applications. This specific model focuses on dual H-bridge functionality within a compact footprint. It complements other variants like the DRV8847 and DRV8849, offering different current ratings and feature sets to suit diverse design requirements in consumer and industrial electronics.
Replacement Considerations
Direct pin-to-pin replacements may include the DRV8847PWP or DRV8849PWP depending on current requirements. Verify compatibility with existing PCB layout and firmware controls. Ensure that alternative parts meet the same voltage and current specifications for seamless integration without redesigning the power stage.
