The UCC27511A-Q1 device is a compact gate driver that offers superior replacement of NPN and PNP discrete driver (buffer circuit) solutions. The UCC27511A-Q1 device is an automotive-grade single-channel low-side, high-speed gate driver rated for MOSFETs, IGBTs, and emerging wide-bandgap power devices such as GaN. The device features fast rise times, fall times, and propagation delays, making the UCD27511A-Q1 device suitable for high-speed applications. The device features 4-A peak source and 8-A peak sink currents with asymmetrical drive, boosting immunity against parasitic Miller turnon effect. The split output configuration enables easy and independent adjustment of rise and fall times using only two resistors and eliminating the need for an external diode.
