INTRODUCTION
The SMS64 is a highly integrated power supply
monitor and controller. The SMS64 has six supply
managers, each individually programmable with
regard to threshold voltages, actions that can be taken
with either an under- or over-voltage condition and
how that manager will operate in sequencing the
power-on operation.
The managers can act independently or sequenced
with any other manager in the device. When the
managers work together the device can control the
sequence in which power is applied to the application
circuits. Each manager is assigned to a sequence
position which allows the device to perform power
supply sequencing in any order. For power-off
situations the SMS64 can sequence the supplies
either in the same order or reverse order from the
power-on sequence.
The SMS64 has two programmable Watchdog
timers, two programmable reset outputs and a
programmable IRQ# output. Using the I
2
C 2-wire
serial interface, a host system can communicate with
the SMS64 status register, optionally control power-on
via software and utilize 4 K-bits of nonvolatile memory.

Power Supply Sequencing and System Start-up Initialization using the SMS64
This is an example application and the specific component values are purposely not shown. The SMS64 can be used with any combination of
MOSFETs, LDOs or DC/DC converters to optimize sequencing and minimize losses in the power chain.
