3 Description

The UCC218915-Q1 is a galvanically isolated single

channel pre-driver designed for SiC MOSFETs and

IGBTs up to 1500V DC operating voltage with

advanced protection features, best-in-class dynamic

performance, and robustness. The UCC218915-Q1

has dual 2.8A outputs for directly driving an external

buffer NMOS/PMOS pair.

The input side is isolated from the output side

with SiO2 isolation technology, supporting up to

1.06kVRMS working voltage, 10kVPK surge immunity

with longer than 40-years isolation barrier life, as

well as providing low part-to-part skew, and >200V/ns

common mode noise immunity (CMTI).

The UCC218915-Q1 includes state-of-art protection

features, such as fast overcurrent and short circuit

detection, controlled soft shutdown after a fault, fault

reporting, active Miller clamp, active short circuit

input on the high-voltage side and input and output

side power supply UVLO to optimize SiC and IGBT

switching behavior and robustness.
