DRV8323RSRGZR

Overview

The DRV8323RSRGZR is a three-phase smart gate driver from Texas Instruments, housed in a 48-pin VQFN package. It operates within a supply voltage range of 6 V to 60 V and supports peak source currents of 1 A and sink currents of 2 A. The device integrates three bidirectional current sense amplifiers with adjustable gain settings via SPI or hardware interfaces. Key features include an integrated buck step-down converter, smart gate drive capabilities with programmable slew rate and dead-time control, and comprehensive protection mechanisms such as over-current, over-temperature, and under-voltage lockout.

Feature Summary

• Integrates three bidirectional current sense amplifiers for precise low-side shunt resistor monitoring
• Features smart gate drive architecture with adjustable slew rate and dead-time control
• Includes an integrated buck step-down converter for internal power management
• Supports configuration via SPI interface or dedicated hardware management pins

Applications

• Brushless DC (BLDC) motor drives
• Sensorless FOC motor control systems
• Industrial automation motor stages
• Multi-phase motor applications requiring integrated current sensing

Procurement Notes

Verify the specific suffix 'RGZR' against the manufacturer's latest datasheet to confirm pinout and packaging details. Ensure compatibility with the intended PCB footprint, specifically the 48-VQFN PowerPAD dimensions. Confirm that the required operating temperature range aligns with the specified -40°C to +125°C limits for your application environment.

Selection Notes

Select this component when a single-chip solution combining gate driving, current sensing, and power regulation is required. It is suitable for designs needing flexible configuration through either software (SPI) or hardware controls. Consider this part for space-constrained applications where integrating external current sense amplifiers and buck converters would otherwise increase board size and complexity.

Part Context

This device belongs to the DRV832x family of three-phase smart gate drivers. It shares architectural similarities with the DRV8323R but utilizes the RS variant designation, typically indicating specific interface or feature configurations within the product line. The RGZR suffix denotes the tape and reel packaging format for surface-mount assembly.

Replacement Considerations

The DRV8323RSRGZT is a compatible alternative offering identical electrical characteristics but supplied in cut-tape packaging instead of reel format.
