Allegro

Datasheet Details

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

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.
