immunity (CMTI), low propagation delay, and small
pulse width distortion. Tight process control results in
small part-to-part skew. The input stage is an
emulated diode (ediode) which means long term
reliability and excellent aging characteristics

5.7-kVRMS single channel isolated gate driver with
opto-compatible input

Pin-to-pin, drop in upgrade for opto isolated gate
drivers
compared to traditional LEDs found in optocoupler
gate drivers. It is offered in a stretched SO6 package
with >8.5mm creepage and clearance, and a mold
compound from material group I which has a
comparative tracking index (CTI) >600V. UCC23511-
Q1's high performance and reliability makes it ideal
for use in automotive motor drives such as the traction
inverter, on-board chargers, DC charging stations,
and automotive HVAC and heating systems. The
higher operating temperature opens up opportunities
for applications not previously able to be supported by
traditional optocouplers.

3 Description
The UCC23511-Q1 is an Opto-compatible, single-
channel, isolated gate driver for IGBTs, MOSFETs and
SiC MOSFETs, with 1.5-A source and 2-A sink peak
output current and 5.7-kVRMS reinforced isolation
rating. The high supply voltage range of 33-V allows
the use of bipolar supplies to effectively drive IGBTs
and SiC power FETs. UCC23511-Q1 can drive both
low side and high side power FETs. Key features and
characteristics bring significant performance and
reliability upgrades over standard opto-coupler based
gate drivers while maintaining pin-to-pin compatibility
in both schematic and layout design. Performance
