1 Introduction

The UCC27614EVM is designed to primarily evaluate the UCC27614DSG performances. The UCC27614DSG is a 30-V, single channel low-side driver with 10-A peak source and 10-A peak sink current for driving Si/IGBTs/SiC and GaN FETs. The UCC27614EVM board can be used to evaluate other pin-to-pin compatible parts in the 2x2mm WSON package. The UCC27614EVM inputs can tolerate signals as high as 26 V regardless of the VDD voltage which enhances device robustness.

2 Description

The UCC27614EVM is designed to primarily evaluate the UCC27614DSG. The driver's performance can be evaluated while driving capacitive loads and/or power devices with provisions for TO-220 footprints. The UCC27614DSG is a 30-V single channel, low-side driver with 10-A peak source and 10-A peak sink current for driving high gate charge MOSFETs. The UCC27614EVM evaluation board use surface-mount test points allowing connection to IN+, IN-, VDD and OUT to evaluate the UCC27614 in the 2x2 WSON package. The EVM is set up to evaluate the UCC27614DSG in an inverting (IN-) and non-inverting (IN+) configuration to drive various capacitive and resistive loads as well TO-220 Si/IGBTs/SiC MOSFETs with a default configuration using a 1.8nF capacitive load.

The UCC27614 has low propagation delays and fast rise (5 ns) and fall (4 ns) times at the driver outputs for reliable timing of the gate drive signals. The UCC27614 inputs can tolerate signals as high as 26-V (max recommended operating conditions) regardless of the VDD voltage which enhances device robustness.
