in my case, i'll use our own mcu to control the drv8301, then use the drv8301 to control the mosfet.
I’ll use the drv8301’s pin50(PH) get the 5.0v
But I cannot now how to set the bulk’s output voltage (why the output is the 5.0v ?)
And I’ll use the 5.0v to generate the mcu_3.3v
As you know, the mcu_3.3v will use for drv8301’s config pin (such as pwrgd , noctw , nfault , en_gate, and vdd_spi),
And the en_bulk is always pull up by PVDD1.
is it ok ( not self-lock ) ?
at the same time, I’ll use the sigma-delta module chip (ti’s amc1304) to sample the mosfet’s current(the net is sh_a).
i connect the amc1304’s ldoin to the drv8301’s bst_a( gate floating voltage ), is it ok ?
Thanks a lot !
