UCC2154x Reinforced Isolation Dual-Channel Gate Driver  
With 3.3-mm Channel-to-Channel Spacing Option  
1 Features  
3 Description  
•
Wide body package options  
The UCC2154x is an isolated dual channel gate driver  
family designed with up to 4-A/6-A peak source/sink  
current to drive power MOSFET, IGBT, and GaN  
transistors. UCC2154x in DWK package also offers  
3.3-mm minimum channel-to-channel spacing which  
facilitates higher bus voltage.  
– DW SOIC-16: pin-2-pin to UCC21520  
– DWK SOIC-14: 3.3 mm Ch-2-Ch spacing  
Up to 4-A peak source and 6-A peak sink output  
Up to 18-V VDD output drive supply  
– 5-V and 8-V VDD UVLO Options  
CMTI greater than 100 V/ns  
•
•
The UCC2154x family 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).  
•
•
Switching parameters:  
– 40-ns maximum propagation delay  
– 5-ns maximum delay matching  
– 5.5-ns maximum pulse-width distortion  
– 35-µs maximum VDD power-up delay  
Resistor-programmable dead time  
TTL and CMOS compatible inputs  
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  
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.
