DRV8320RSRHAT

Overview

The DRV8320RSRHAT is a three-phase smart gate driver from Texas Instruments, designed for brushless DC (BLDC) and permanent magnet synchronous motor (PMSM) applications. It integrates high-side and low-side N-channel MOSFET drivers with an operating voltage range of 6V to 60V. The device features integrated current shunt amplifiers for phase current sensing, enabling closed-loop control without external components. Packaged in a 48-pin HTQFP (RSH) format, it supports PWM frequencies up to 300kHz. Key electrical parameters include a peak output drive current of 2A and a quiescent supply current of 15mA. The operational temperature range spans from -40°C to +125°C, ensuring reliability in industrial environments.

Feature Summary

• Integrates three-phase gate drivers with built-in current shunt amplifiers for simplified sensorless or sensored motor control designs
• Supports high-frequency PWM operation up to 300kHz with adjustable dead-time control to prevent shoot-through
• Features comprehensive protection mechanisms including over-current protection, under-voltage lockout, and thermal shutdown

Applications

• Industrial BLDC and PMSM motor drives
• Robotics actuator control systems
• HVAC fan and pump motor controllers

Procurement Notes

Verify the specific suffix 'RSH' confirms the 48-pin HTQFP package variant when sourcing. Ensure the component meets RoHS compliance standards required for your assembly process. Cross-reference the datasheet revision date to confirm alignment with your design's timing requirements. Validate that the supplier provides original manufacturer packaging to guarantee authenticity and storage integrity.

Selection Notes

Select this component when a single-chip solution for three-phase motor driving and current sensing is required. It is suitable for designs needing integrated protection against over-current and thermal events. Consider the 60V maximum rating for compatibility with standard bus voltages. Evaluate the HTQFP package for PCB space constraints and thermal dissipation needs relative to alternative QFN packages.

Part Context

This part belongs to the DRV832x family of smart gate drivers, which are optimized for efficient motor control applications. It serves as a bridge between microcontroller logic signals and power stage MOSFETs. The integration of shunt amplifiers distinguishes it from basic gate drivers by reducing external component count. It complements TI's broader portfolio of motor control ICs and evaluation modules.

Replacement Considerations

The DRV8320RTHT is a pin-compatible alternative in a different package. The DRV8328 offers similar functionality but with lower current ratings. Verify pin-to-pin compatibility and parameter overlaps before substitution. Consult official cross-reference guides for confirmed equivalents.
