UCC21530: Query for programmable dead-time

Part Number: UCC21530

Dear Sir/Mam,

I need to use IC UCC21530 for SIC-MOSFET gate driver application, which have the capability for programmable dead time. However, there is no description on upper and lower limit of dead-time in datasheet.

A formulae is provided which describes a linear relationship between DT and resistor. My query is what is the lowest value resistor that I can place in this application. An example of 20 kOhm resistor is provided in datasheet. Whether we can use 0.5 kOhm resistor to get dead-time of 50 ns. 

Kindly provide the lower and upper limit of settable dead-time.
