2.1 Features

The EVM supports the following features:

  • EVM for the low-voltage features of the UCC27624 gate driver
  • 4.5-V to 26-V VCC power supply range
  • 5-A source, 5-A sink current
  • -10V input voltage capability
  • TTL-compatible inputs
  • PCB layout optimized for bias supply bypassing cap, gate-drive resistance selection
  • Capacitive load, external gate drive resistor and TO-220 footprint for N-ch MOSFETs gate drive network evaluation
  • Ability to parallel both OUTA and OUTB channels for higher pulsed output current
  • Allows quick verification of most of the data sheet parameters
  • Test points allow probing all the key pins of the UCC27624
