technology. The
LA-ispPAC-POWR1014/A device provides 10 indepen-
dent analog input channels to monitor up to 10 power
supply test points. Each of these input channels has
two independently programmable comparators to sup-
port both high/low and in-bounds/out-of-bounds (win-
dow-compare) monitor functions. Four general-purpose
digital inputs are also provided for miscellaneous con-
trol functions.
The LA-ispPAC-POWR1014/A provides 14 open-drain
digital outputs that can be used for controlling DC-DC
converters, low-drop-out regulators (LDOs) and opto-
couplers, as well as for supervisory and general-pur-
pose logic interface functions. Two of these outputs
(HVOUT1-HVOUT2) may be configured as high-voltage
