Other Parts Discussed in Thread: LM74800-Q1, TINA-TI
Tool/software:
Hi, I have been doing some simulating of LM74801-Q1 in a common source configuration (using TINA-TI). I am attempting to use this for a relatively high power application (in comparison to the reference design). I am noticing that at large load currents the forward voltage drop of the ideal diode MOSFET is increasing and preventing Vcap from recharging after Vds of Q2 reaches 150mV. I am wondering if this is due to some hidden threshold (I wasn't able to find advertised on the datasheet) that is causing this to happen? Furthermore, is behavior an artifact the 10.5 mV V(ac) linear forward voltage regulation feature which is unique to LM74800-Q1? Might LM74801-Q1 behave differently?
