Overview
The DRV8424PWPR is a dual H-bridge stepper motor driver manufactured by Texas Instruments, designed for bipolar stepper motors and dual brushed DC motors. It features an integrated current sense amplifier and smart tune technology to simplify tuning. The device supports a STEP/DIR interface and offers up to 1/256 microstepping resolution. Key electrical parameters include a supply voltage range of 4.5 V to 33 V, a maximum output current of 2.5 A per bridge, and operation within a temperature range of -40°C to +125°C. It is housed in a thermally enhanced HTSSOP-28 package with a PowerPAD.
Feature Summary
- Integrated current sense amplifier eliminates the need for external shunt resistors and amplifiers.
- Smart tune technology automatically optimizes PWM frequency and blanking time based on motor characteristics.
- Supports high-resolution motion control with selectable microstepping modes up to 1/256 step resolution.
Applications
- Bipolar stepper motor control in office automation equipment
- Dual brushed DC motor drives in industrial automation
- Printers and scanners requiring precise positioning
Procurement Notes
Verify the exact suffix PPWPR against the manufacturer's latest datasheet to confirm the HTSSOP-28 package and reel packaging specifications. Ensure that the ordering part number matches the specific thermal and electrical ratings defined in the official TI documentation before procurement.
Selection Notes
Select this component when designing systems requiring integrated current sensing and automatic tuning capabilities for stepper or DC motors. Consider the 2.5 A output capability and 33 V maximum supply voltage limits relative to the load requirements. Evaluate the HTSSOP-28 package size and thermal performance for space-constrained PCB layouts.
Part Context
This part belongs to the DRV8424E/P family of dual H-bridge motor drivers from Texas Instruments. It is engineered for applications demanding high precision and simplified design cycles through integrated signal conditioning and adaptive control features, distinguishing it from basic gate drivers.
Replacement Considerations
Direct substitutes within the same family include the DRV8424PRGER, which shares identical electrical specifications but utilizes a different QFN package (RGYR) compared to the PWPR's HTSSOP form factor. Cross-package replacements require careful review of thermal dissipation and pinout compatibility.
