A4919 - Three-Phase MOSFET Driver

General Description

The A4919 is a three-phase controller for use with N-channel external power MOSFETs.

A unique charge pump regulator provides full (>10 V) gate drive at power supply voltages down to 7 V and allows the A4919 to operate with reduced gate drive at power supply voltages down to 5.5 V.

Key Features

  • High-current 3-phase gate drive for N-channel MOSFETs.
  • 5.5 to 50 V supply voltage range.
  • Regulated logic supply voltage output option.
  • Low-current Sleep mode option.
  • Motor phase short-to-supply and short-to-ground detection.
  • Cross-conduction protection.
  • Undervoltage, overtemperature monitors.
