Other Parts Discussed in Thread: BQ25792, BQ24800
Hello all,
I'm evaluating the BQ25792 using the BQ25792EVM.
I use a single USB input as shown:
I measured the load switch rise time during a VBUS hot plug, and it was about 100usec.
In order to reduce inrush current caused by a relatively hi VBUS capacitance (2x10uF on VBUS + 3x10uF on PMID), I need a bit more than 100usec rise time...more like 500usc - 1msec.
Is it possible to add a RC circuit to the ACDRV pin (as shown above) in order to slow down the FET rise time?
I would appreciate other suggestions if there is simpler solution.
Thanks!
Nir
