| Texas Instruments' UCC27531 represents industry best in class in terms of single-channel gate driver ICs for IGBTs, and integrates the best features of the best driver ICs available in the market. The devices are universal, single low-side drivers that are a good fit in low-to-high frequency and low-to-high power applications.
The UCC27531 is a single-channel, high-speed, gate driver capable of effectively driving MOSFET and IGBT power switches by up to 2.5 A source and 5 A sink (asymmetrical drive) peak current. Strong sink capability in asymmetrical drive boosts immunity against parasitic Miller turn-on effect. It also features a split-output configuration where the gate-drive current is sourced through OUTH pin and sunk through OUTL pin. This pin arrangement allows the user to apply independent turn-on and turn-off resistors to the OUTH and OUTL pins, respectively, and easily control the switching slew rates.
