The UCC2773x-Q1 is a 700V half-bridge gate driver with 3.5A source and 4A sink current capability, targeted to drive power MOSFETs and IGBTs. The device comprises of one ground-referenced channel (LO) and one floating channel (HO) which is designed to drive half-bridge configured MOSFETs and IGBTs operating with bootstrap supplies. The device features robust drive with excellent noise and transient immunity including large negative voltage tolerance on its inputs, high dV/dt tolerance, wide negative transient safe operating area (NTSOA) on the switch node (HS), and interlock.

The device accepts a wide range of bias supply input from 10V to 21V and offers UVLO protection for both the VDD and HB bias supply pins. The UCC2773x-Q1 is available in various packages and is rated to operate from –40°C to 150°C.

UCC27735Q1EVM — UCC27735-Q1 評估模組

UCC27735-Q1 評估模組 (EVM) 的開發旨在評估 UCC27735-Q1 驅動器性能，並與產品規格表的參數進行比較，亦可從外部連接至電源裝置，提供源極和汲極閘極電阻靈活度。UCC27735Q1EVM 評估板使用表面裝載測試點，可連接至 LI、HI、VDD 及 HB 輸入。提供各種其他測試點來探測 UCC27735-Q1。配置輸入偏壓後，即可從 VCC 取得 VHB-VHS 高壓側偏壓，亦可新增外部額外偏壓，直接提供 VHBVHS。高壓側和低壓側驅動器輸出迴路分別在 HS 和 GND 上分離，以評估 UCC27735-Q1 HS 負電壓能力。
