Texas Instruments  UCC27511ADBVT

The UCC27511A device is a compact gate driver thatoffers superior replacement of NPN and PNP discrete driver (buffer circuit) solutions. TheUCC27511Asingle-channel low-side,high-speed gate driver rated for MOSFETs, IGBTs, and emerging wide-bandgap power devices such asGaN. The device features fast rise times, fall times, and propagation delays, making theUCC27511A device suitable for high-speed applications. Itsasymmetrical 4-A peak source and 8-A peak sink currents boost immunity against parasitic Millerturnon effect. The split output configuration enables easy and independent adjustment of rise andfall times using only two resistors and eliminating the need for an external diode. Featuresincluding wide input hysteresis and negative input voltage handling enhance transient immunity.
