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 评估模块

UCC27735-Q1 评估模块 (EVM) 开发用于评估 UCC27735-Q1 驱动器性能并将其与数据表参数进行比较，或者从外部连接到功率器件以提供灵活的拉电流和灌电流栅极电阻。UCC27735Q1EVM 评估板使用表面贴装测试点，允许连接到 LI、HI、VDD 和 HB 输入。可通过各种其他测试点来探测 UCC27735-Q1。输入偏置经过专门配置，使得 VHB-VHS 高侧偏置可以来自 VCC，或者可以添加外部额外偏置以直接提供 VHBVHS。高侧和低侧驱动器输出回路分别在 HS 和 GND 上分开，以便评估 UCC27735-Q1 HS 负电压能力。
