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.

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
