DRV8304 - 38-V 3-Phase Smart Gate Driver

General Description

The DRV8304 device is an integrated gate driver for 3-phase brushless DC (BLDC) motors applications for 12-V and 24-V DC rails.

These applications include field-oriented control (FOC), sinusoidal current control, and trapezoidal current control of BLDC motors.

Key Features

  • 1 6-V to 38-V, Triple Half-Bridge Gate Driver With Integrated 3x Current Sense Amplifiers (CSA).
  • 40-V Absolute Maximum Rating.
  • Fully Optimized for 12-V and 24-V DC Rails.
  • Drives High-Side and Low-Side N-Channel MOSFETs.
  • Supports 100% PWM Duty Cycle.
  • Smart Gate-Drive Architecture.
  • Adjustable Slew-Rate Control for Better EMI and EMC Performance.
  • VGS Hand-Shake and Minimum Dead-Time Insertion to Avoid Shoot-Through.
  • 15.
