Power Manager II ispPAC-POWR6AT6
The ispPAC-POWR6AT6-01-SN32 Power Manager II device is a 32-ball QFNS package programmable mixed-sig-
nal PLD which provides an interface between the on-board current sensor circuit and the I
2
C interface bus. The
POWR6AT6 provides analog voltage monitors (VMON) and a 10-bit ADC to provide voltage measurements and an
I
2
C interface to the LC4256ZE CPLD. The 15x2 External Header Landing provides access to VMON3 and VMON4
inputs for experiments with external circuit monitoring.

Power Supply
Two optional power sources are provided depending on jumper settings. A 3.0V supply rail is provided from the bat-
tery and can power a subset of the board including the ispMACH 4000ZE, current sensor circuit, and LCD panel.
Alternatively 3.3V and 1.8V supply rails are converted from the USB 5V interface when the board is connected to a
host PC. The ispMACH4000ZE device will be isolated from other subsystems to accommodate accurate cur-
rent/power measurements.
