Description
Lattice’s Power Manager II ispPAC-POWR6AT6 is a
general-purpose power-supply monitoring and margin-
ing controller, incorporating in-system programmable
analog functions implemented in non-volatile E
technology. The ispPAC-POWR6AT6 device provides
six independent analog input channels to monitor up to
six power supply test points. Each of these input chan-
nels offers a differential input to support remote ground
sensing.
2
CMOS
The ispPAC-POWR6AT6 incorporates six DACs for gen-
erating a trimming voltage to control the output voltage
of a power supply. The trimming voltage can be set to
four hardware selectable preset values (voltage profiles)
or can be dynamically loaded in to the DAC through the
I
C bus. Additionally, each power supply output voltage
can be maintained typically within 0.5% tolerance
across various load conditions using the Digital Closed
Loop Control mode. The operating voltage profile can
be selected using external hardware pins.
