33-V maximum output drive voltage (VDD-VEE)  
±10-A drive strength and split output  
150-V/ns minimum CMTI  
270-ns response time fast overcurrent protection  
Internal 2-level turn-off when fault happens  
Isolated analog sensor with PWM output for  
– Temperature sensing with NTC, PTC or thermal  
diode  
– High voltage DC-Link or phase voltage  
Alarm FLT on over current and reset from RST/EN  
Fast enable/disable response on RST/EN  
Reject <40-ns noise transient and pulse on input

SOIC-16 DW package with creepage and  
clearance distance > 8 mm  
The UCC21732 is a galvanic isolated single channel  
gate driver designed for SiC MOSFETs and IGBTs up  
to 2121-V DC operating voltage with advanced  
protection features, best-in-class dynamic  
performance and robustness. UCC21732 has up to  
±10-A peak source and sink current.  
The input side is isolated from the output side with  
SiO2 capacitive isolation technology, supporting up to  
1.5-kVRMS working voltage, 12.8-kVPK surge immunity  
with longer than 40 years Isolation barrier life, as well  
as providing low part-to-part skew , >150V/ns  
common mode noise immunity (CMTI).  
•

•
The UCC21732 includes the state-of-art protection  
features, such as fast overcurrent and short circuit  
detection, shunt current sensing support, fault  
reporting, active miller clamp, input and output side  
power supply UVLO to optimize SiC and IGBT  
switching behavior and robustness. The isolated  
analog to PWM sensor can be utilized for easier  
temperature or voltage sensing, further increasing the  
drivers' versatility and simplifying the system design  
effort, size and cost.
