Description
Lattice’s Power Manager II ispPAC-POWR1014/A is a
general-purpose power-supply monitor and sequence
controller, incorporating both in-system programmable
logic and in-system programmable analog functions
implemented in non-volatile E
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 inde-
pendently programmable comparators to support both
high/low and in-bounds/out-of-bounds (window-com-
pare) monitor functions. Four general-purpose digital
inputs are also provided for miscellaneous control func-
tions.

technology. The
The ispPAC-POWR1014/A provides 14 open-drain digi-
tal outputs that can be used for controlling DC-DC con-
verters, 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
