UCC27531 Overview
Description
The UCC2753x single-channel, high-speed gate drivers can effectively drive MOSFET and IGBT power switches. Using a design that allows for a source of up to 2.5 A and 5-A sink through asymmetrical drive (split outputs), coupled with the ability to support a negative turn-off bias, rail-to-rail drive capability, extremely small propagation delay (17 n.
Key Features
- 1 Low-cost gate driver (offering optimal solution for driving FET and IGBTs)
- Superior replacement to discrete transistor pair drive (providing easy interface with controller)
- TTL and CMOS compatible input logic threshold (independent of supply voltage)
- Split output options allow for tuning of turnon and turnoff currents
- Inverting and noninverting input configurations
- Enable with fixed TTL compatible threshold
- High 2.5-A source and 2.5-A or 5-A sink peak drive currents at 18-V VDD
- Wide VDD range from 10 V to 35 V
- Input and enable pins capable of with standing up to –5-V DC below ground
- Output held low when inputs are floating or during VDD UVLO
