INTRODUCTION
The SMS66 is a very accurate programmable power
supply supervisor that monitors and sequences. It
controls sequencing time and position of up to six
isolated or non-isolated distributed or POL DC/DC
converters. The monitor supervisory function has two
independent UV and OV settings for each supply and
can be set in 5mV steps. The SMS66 also sequences
the power supplies in any order using enable outputs
with programmable polarity.
The SMS66 monitors six power supply channels as
well as VDD, 12V input, two general-purpose analog
inputs and an internal temperature sensor using a 10-
bit ADC. The 10-bit ADC can measure the value on
any one of the input channels and output the
conversion data via the I
C bus.
Using the I
2
C interface, a host system can
communicate with the SMS66 status register,
optionally control Power-on/off, and utilize 4 K-bits of
nonvolatile memory.
