DETAILED PIN DESCRIPTIONS

◆ Power supply pins

The power supply of MAS9560 is divided into

functional sections so that:

ƒ DVSS is connected internally with all digital

parts

ƒ IOVDD and DVSS are connected internally with

all digital inputs and outputs

ƒ DVSS is ground connection for all digital parts

ƒ All GND pins are internally connected together

ƒ LSVDD and VBAT are internally connected

together

Other power supply pins should be connected as

follows:

ƒ VLDO should be connected to VBAT in non-

LDO mode. If LDO mode is selected, VLDO is

the output of LDO.

ƒ HPVDD and EPVDD can be driven by VLDO in

LDO mode to reduce power supply noise

ƒ HPVSS, EPVSS, LSVSS must be connected to

analog ground (AVSS). The pins are internally

connected together.
