Output stage gate drivers

3 April 2013 Power Electronics / Power Management

Texas Instruments introduced two 35 V, single-channel, output stage power management gate drivers for insulated-gate bipolar transistors (IGBTs) and silicon carbide (SiC) FETs. The UCC27531 and UCC27532 with split output provide efficient output drive capability, short propagation delay (17 ns typical) and increased system protection for isolated power designs such as solar DC-AC inverters, uninterruptible power supplies and electric vehicle charging. The devices prevent digital controllers from operating too close to the power circuitry, extending the lifetime of isolated power designs. Peak current of 2,5 A source and 5 A sink allows fast charging of IGBTs and ensures reliable and efficient operation.
