Other Parts Discussed in Thread: CSD17382F4, CSD17381F4
i investigate the datasheet of the LM5134. and i find out that if some one want to use the PILOT ability, they must add extra Mosfet to the gate drive. but in datasheet there is a section that guide how to choose this Mosfet "PILOT MOSFET Selection".
in this section TI compmany suggest that it is better to chose a Mosfet with these specification:
In general, a small-sized 20-V MOSFET with logic level gates can be used as the external turnoff switch. To
achieve a fast switching speed and avoid the potential shoot-through, select a MOSFET with the total gate
charge less than 3 nC.
a Mosfet with just gate charge less than 3 nC!!!!!!!!!!!!!!!!???
how can we find a cheap Mosfet with these specifications
would please introduce a cost effective Mosfet for this gate drive?
thank you very much
