AHV85000 - GaN FET Isolated Gate Driver

General Description

The AHV85000 + AHV85040 is a cost-optimized isolated gatedrive chipset for gallium-nitride (GaN) field-effect-transistor (FET) devices.

Key Features

  • Chipset transmits both PWM signal and bias power through a single external isolation transformer.
  • No high-side bootstrap.
  • No external secondary-side bias supply.
  • 50 ns propagation delay (with recommended transformers).
  • Separate drive output pins: pull-up (2.8 Ω) and pull-down (1.0 Ω).
  • Supply voltage 10.5 V < VDRV < 13.2 V.
  • Undervoltage lockout on primary VDRV and secondary VSEC.
  • Enable pin with fast response.
  • Conti.
