AHV85111 Datasheet Self-powered Single-channel Isolated Ganfet Driver

Manufacturer: Allegro MicroSystems

Overview: AHV85111 Self-Powered Single-Channel Isolated GaN FET Driver with Regulated Bipolar Output.

General Description

The AHV85111 isolated gate driver is optimized for driving GaN FETs in multiple applications and topologies.

An isolated dual positive/negative output bias supply is integrated into the driver, eliminating the need for any external gate drive auxiliary bias supply or high-side bootstrap.

The bipolar output rails, with adjustable and regulated positive rail, improves dv/dt immunity, greatly simplifies the system design, and reduces EMI through reduced total common-mode (CM) capacitance.

Key Features

  • Transformer isolation barrier.
  • Power-Thru integrated isolated bias.
  • No need for high-side bootstrap.
  • No need for external secondary-side bias.
  • AEC-Q100 Grade 2 qualification.
  • Bipolar drive output with adjustable regulated positive rail.
  • Built-in primary-side 3.3 V REF bias output.
  • 50 ns propagation delay.
  • Supply voltage 10.8 V < VDRV < 13.2 V.
  • Undervoltage lockout on primary VDRV and secondary VSEC.
