DETAILED PIN DESCRIPTIONS
◆
Power supply pins
The power supply of MAS9560 is divided into
functional sections so that:
DVSS is connected internally with all digital
parts
IOVDD and DVSS are connected internally with
all digital inputs and outputs
DVSS is ground connection for all digital parts
All GND pins are internally connected together
LSVDD and VBAT are internally connected
together
Other power supply pins should be connected as
follows:
VLDO should be connected to VBAT in non-
LDO mode. If LDO mode is selected, VLDO is
the output of LDO.
HPVDD and EPVDD can be driven by VLDO in
LDO mode to reduce power supply noise
HPVSS, EPVSS, LSVSS must be connected to
analog ground (AVSS). The pins are internally
connected together.
