Part Number:LP87564-Q1
Hello,
My customer would like to know if there is a way to configure the ENx pins as individual PGOOD for BUCKx, for example, configure EN1 as a GPIO output and report PGOOD status of BUCK1 directly?
They want to use these pins for power sequence. Since there are 4 bucks in LP87564, they want to ramp up BUCK0 and BUCK1 first, then use PGOOD of BUCK1 to enable an external regulator. When the external regulator is up, continue BUCK3 and BUCK4 ramp.
They prefer this configuration be loaded at bootup; after that, no software involvement is needed.
I did not see a way to configure ENx pins as individual PGOOD signals in the datasheet, but I believe an individual PGOOD could be output from the PGOOD pin or nINT pin with proper masking of PG or Interrupt controls, is that correct?
Thanks,
Alan
