DRV8317 - Three-Phase PWM Motor Driver

Description

DRV8317 provides three integrated MOSFET halfbridges for driving three-phase brushless DC (BLDC) motors with 5-V, 9-V, 12-V, or 18-V DC rails or 2s to 4s batteries.

The device provides integrated threephase current sensing which eliminates the need for external sense resistors.

Features

  • Three-phase BLDC motor driver.
  • Configurable slew rate for EMI mitigation.
  • Programmable gain current sensing.
  • Supports up to 200-kHz PWM frequency.
  • Integrated shoot through protection.
  • 4.5-V to 20-V operating voltage.
  • 24-V absolute maximum voltage.
  • High output current capability.
  • 5-A peak current drive.
  • Low on-state resistance MOSFETs.
  • RDS(ON) (HS + LS) at TA = 25°C : 130-mΩ (typical).
  • Ult.
