The UCC21222-Q1 device can be configured as two low side drivers, two high side drivers, or a half-bridge driver. 5ns delay matching performance allows two outputs to be paralleled, doubling the drive strength for heavy load conditions without risk of internal shoot-through.
The input side is isolated from the two output drivers by a 3.0kVRMS isolation barrier, with a minimum of 100V/ns Common-Mode Transient Immunity (CMTI).
Resistor programmable dead time gives the capability to adjust dead time for system constraints to improve efficiency and prevent output overlap.
Other protection features include: Disable feature to shut down both outputs simultaneously when DIS is set high, integrated deglitch 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.
