The ispPAC-POWR1014/A device provides 10 independent analog input channels to monitor up to 10 power supply test points. Each of these input channels has two independently programmable comparators to support both high/low and in-bounds/out-of-bounds (window-compare) monitor functions. Four general-purpose digital inputs are also provided for miscellaneous control functions. The ispPAC-POWR1014/A provides 14 open-drain digital outputs that can be used for controlling DC-DC converters, low-drop-out regulators (LDOs) and optocouplers, as well as for supervisory and general-purpose logic interface functions. Two of these outputs (HVOUT1-HVOUT2) may be configured as high-voltage
