The NCP45496 is a high−performance monolithic IC which can be
used to monitor the power on two high−voltage power supplies
simultaneously. The voltage and current on each bus are measured and
converted to a power signal that is output as a current. The power of
multiple busses may be summed by connecting the power current
signals (IPWRx). The power signal for each channel is also sampled
by an internal ADC and made available over an SVID bus. It also
includes a low−latency open−drain ALARM signal that is produced by
comparing the power of each bus to its individually programmable
threshold level. If either bus exceeds the programmed power threshold
the low−latency ALARM signal will be pulled low. The SVID bus is
used to program the ALARM levels.
