Two regulators with the same order number are not allowed, except for 000 or 111 code. Enable bit in OTP

cells (EnLDO, EnBoost and EnVref) must be set to '1' too, to have the regulator ON in ACTIVE phase. All the

regulators with 111 code can be turned on in ACTIVE mode, when the SPI is available.

Regulators turning on delay after Power Good: the delay is the same for all the regulators.

•

00 = no delay

•

01 = 2 ms after PGOOD of previous regulator

•

10 = 5 ms after PGOOD of previous regulator

•

11 = 10 ms after PGOOD of previous regulator

•

Reset activation related to the right regulator Power Good (2 bits)

–

00 = Reset release after PGOOD of the BUCK with a delay from 0 (no delay) to 10 ms (2 bits)

–

01 = Reset release after PGOOD of the second regulator with a delay from 0 (no delay) to 10 ms (2

bits)

–

10 = Reset release after PGOOD of the third regulator with a delay from 0 (no delay) to 10 ms (2 bits）

–

11 = Reset release when ACTIVE state is reached (unconditional Reset release)
