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.

评估板

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。
