Hello,
my circuit is running. I try to switch the N-FET
IRLR2905TRLPBF (https://www.mouser.de/datasheet/2/196/irlr2905pbf-1228485.pdf)
but the charging pump is not working working. The voltage is too less.
I use the same circuit like in the datasheet (https://www.analog.com/media/en/technical-documentation/data-sheets/4440fb.pdf page 1). The difference is, that I use only the High-side switch and I have only the N FET connected.
Is it possible, that there must be an resistor load at the TS pin?
Best reagrds,
Dirk Seidel
