The UCC2773x 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 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。
