DRV8704DCP

Overview

The DRV8704DCP is a stepper pre-driver manufactured by Texas Instruments, housed in a 38-HTSSOP surface-mount package. It operates within a supply voltage range of 0V to 5.3V and supports load voltages from 8V to 52V. The device features an operating frequency of 500 kHz and draws a typical working supply current of 17 mA. It provides a 5 V output voltage and delivers an output current of 10 mA. Designed for industrial environments, it functions reliably between -40°C and +85°C ambient temperatures.

Feature Summary

• Supports PWM and SPI interfaces for motor control
• Integrates controller functions for commutation and direction management
• Utilizes NMOS technology for power stage driving

Applications

• Stepper motor pre-driving applications
• General purpose motor control systems

Procurement Notes

Verify the specific suffix 'DCP' corresponds to the tube packaging format rather than the reel variant. Confirm component status as discontinued or obsolete through official Texas Instruments channels before finalizing procurement plans. Ensure compatibility with existing PCB footprints for the 38-HTSSOP package.

Selection Notes

Select this component when a dedicated stepper pre-driver interface is required alongside main motor drivers. Consider the 38-pin form factor for board space constraints. Verify that the 0V to 5.3V logic supply range aligns with the system's microcontroller or control unit voltage levels.

Part Context

This part belongs to the DRV8704 series of motor controllers and drivers. It serves as a specialized pre-driver stage, distinct from integrated full-bridge solutions like the DRV8704EVM platform. The series focuses on providing configurable gate drive signals for external power stages.

Replacement Considerations

The DRV8704DCPR is listed as a manufacturer-recommended alternative, differing primarily in reel packaging.
