Frequently Asked Questions
What unique feature does the 'A' version of this modulator include?
The A versions feature an internal discharge transistor on the CS pin, which helps minimize current sense delay.
What are the peak sink and source currents available for OUTA/OUTB?
The outputs can handle a peak sink current of 1.0 A and a peak source current of -0.5 A.
How is the dead time controlled between the two outputs?
Dead time is typically 60 ns to 200 ns, depending on the values selected for the timing capacitor and resistors.
Can I use this device in automotive applications?
Only if the specific UCC2808A product is designated by TI as compliant with ISO/TS 16949 requirements.
