Isolated gate drivers
30 April 2019
Power Electronics / Power Management
Texas Instruments introduced new isolated gate drivers that provide high levels of monitoring and protection for high-voltage systems. The UCC21710-Q1, UCC21732-Q1 and UCC21750 target designs in traction inverters, onboard chargers, solar inverters and motor drives. The devices offer integrated sensing features for IGBTs and SiC MOSFETs to simplify designs and enable greater system reliability in applications operating up to 1,5 kVRMS. With integrated components, the devices provide fast detection time to protect against over-current events while ensuring safe system shutdown. Utilising capacitive isolation technology, they maximise insulation barrier lifetimes while providing high reinforced isolation ratings, fast data speeds and high-density packaging.
