BD71847AMWV and BD71850MWV are programmable Power Management ICs for powering
|
|
single-core, dual-core, and quad-core SoCs such as NXP-i.MX 8M. It is
|
|
optimized for low BOM cost and compact solution footprint. BD71847MWV and
|
|
BD71850MWV integrate 6 Buck regulators and 6 LDOs.

# The BD71847 abd BD71850 support two different HW states as reset target
|
|
# states. States are called as SNVS and READY. At READY state all the PMIC
|
|
# power outputs go down and OTP is reload. At the SNVS state all other logic
|
|
# and external devices apart from the SNVS power domain are shut off. Please
|
|
# refer to NXP i.MX8 documentation for further information regarding SNVS
|
|
# state. When a reset is done via SNVS state the PMIC OTP data is not reload.
|
|
# This causes power outputs that have been under SW control to stay down when
|
|
# reset has switched power state to SNVS. If reset is done via READY state the
|
|
# power outputs will be returned to HW control by OTP loading. Thus the reset
|
|
# target state is set to READY by default. If SNVS state is used the boot
|
|
# crucial regulators must have the regulator-always-on and regulator-boot-on
|
|
# properties set in regulator node.
