UCC21540-Q1  
SLUSDO2C – JUNE 2020 – REVISED FEBRUARY 2021  
UCC21540-Q1 Reinforced Isolation Dual-Channel Gate Driver  
1 Features  
3 Description  
AEC Q100 qualified with:  
– Device temperature grade 1  
The UCC21540-Q1 device is an isolated dual channel  
gate driver with programmable dead time and wide  
temperature range. This device exhibits consistent  
performance and robustness under extreme  
temperature conditions. It is designed with 4-A peak-  
source and 6-A peak-sink current to drive power  
MOSFET, IGBT, and GaN transistors.  
– Device HBM ESD classification level H2  
– Device CDM ESD classification level C6  
Functional Safety Quality-Managed  
Documentation available to aid functional safety  
system design  
The UCC21540-Q1 can be configured as two low-side  
drivers, two high-side drivers, or a half-bridge driver.  
The input side is isolated from the two output drivers  
by a 5.7-kVRMS isolation barrier, with a minimum of  
100-V/ns common-mode transient immunity (CMTI).  
Junction temperature range –40°C to 150°C  
Up to 18-V VDD output drive supply  
– 5-V and 8-V VDD UVLO Options  
CMTI greater than 100 V/ns  
Switching parameters:  
Protection features include: resistor programmable  
dead time, disable feature to shut down both outputs  
simultaneously, integrated de-glitch filter that rejects  
input transients shorter than 5ns, and negative  
voltage handling for up to –2V spikes for 200ns on  
input and output pins. All supplies have UVLO  
protection.  
– 40-ns maximum propagation delay  
– 5-ns maximum delay matching  
– 5.5-ns maximum pulse-width distortion  
– 35-µs maximum VDD power-up delay  
Safety-related certifications:  
– 8000-VPK reinforced isolation per DIN V VDE V  
0884-11:2017-01  
– 5700-VRMS isolation for 1 minute per UL 1577  
– CQC certification per GB4943.1-2011
