DRV8320HRTVT

Overview

The DRV8320HRTVT is a three-phase smart gate driver manufactured by Texas Instruments, designed for brushless DC motor control applications. It integrates six high-side and low-side half-bridge drivers within a single WQFN-32 package. The device supports a supply voltage range from 6 V to 60 V and delivers an output current of 1 A per channel. It features hardware management interfaces alongside SPI/I2C connectivity for configuration. The component operates reliably across a temperature range of -40°C to +125°C and includes shutdown functionality.

Feature Summary

• Integrates three-phase smart gate drive capabilities with hardware management interfaces
• Supports digital communication via SPI and I2C protocols for system control
• Provides integrated high-side and low-side half-bridge driver outputs

Applications

• Brushless DC (BLDC) motor controllers
• Three-phase motor motion control systems
• Industrial automation drives

Procurement Notes

Verify the specific suffix RTVT against official Texas Instruments documentation to confirm the reel packaging format and moisture sensitivity level. Ensure compatibility with the WQFN-32 footprint requirements during procurement planning. Cross-reference the datasheet revision history to validate the latest electrical specifications and thermal characteristics before finalizing orders.

Selection Notes

Select this component when a compact solution for three-phase BLDC motor driving is required. The integration of smart gate drive features reduces external component count compared to discrete solutions. Consider the 60 V maximum supply limit and the 1 A output current capability to ensure suitability for the target motor load. Verify that the WQFN-32 package size fits the available PCB real estate constraints.

Part Context

This part belongs to the DRV8320 series of smart gate drivers from Texas Instruments. It is specifically engineered for efficient control of three-phase motors. The series typically pairs with evaluation modules like the BOOSTXL-DRV8320H for development purposes. It falls under the broader category of power management ICs and motor controllers within the manufacturer's portfolio.

Replacement Considerations

The DRV8320SRTVT is a documented variant within the same family. Both share identical driver counts, output currents, and interface types. Differences may exist in internal circuit optimizations or specific performance thresholds defined in their respective datasheets. Consult the official substitution guide for detailed parameter comparisons.
