Single-Channel Isolated Gate Driver
1 Features
3 Description
•
5.7-kVRMS single channel isolated gate driver with
The UCC23511 is an Opto-compatible, single-
opto-compatible input
Pin-to-pin, drop in upgrade for opto isolated gate
drivers
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 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
highlights include high common mode transient
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
compared to traditional LEDs. 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's high performance and reliability makes it
ideal for use in all types of motor drives, solar
inverters, industrial power supplies, and appliances.
The higher operating temperature opens up
opportunities for applications not previously able to be
supported by traditional optocouplers.
