Allegro Microsystems AHV85110 | Demoboard APEK85110-D1-E

Description

The Allegro APEK85110-D1-E Half-Bridge Driver Switch Board is a demo board containing two AHV85110 GaN FET drivers and two GaN FETs in a half-bridge configuration.The APEK85110 can be used to perform double pulse tests (see Double Pulse Test section) or to interface the half bridge to an existing LC power section, as shown below.The isolated AHV85110 driver does not require secondary-side power or bootstrap components. Gate drive power is supplied to the secondary side from the primary-side supply voltage, VDRV. The amplitude of the gate drive can be varied by varying VDRV between 7 and 15 V.

Features

• Power-Thru integrated isolated bias
• No high-side bootstrap
• No external secondary-side bias
• 50 ns propagation delay, with excellent device-to-device matching of 5 ns
• 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

Typical applications

• Automotive – OBC, Traction Drive
• Grid Infrastructure – Micro-Inverters, solar
• Industrial – Transportation, Robotics, AC-DC and DC-DC converters – totem-pole PFC, Half-/Full-Bridge, LLC, SR Drive, multi-level converters, phase-shifted full-bridge, etc.
