Note: R102 is only needed for BSCAN mode.
If BSCAN is not used, leave MODE_0 and
MODE_1 floating since both pins are default pull
down.
MODE PIN
00 = Native mode
11 = Boundary Scan-(BSCAN) mode
Remove R113 at EVT if no issue found
Place near MSM
R117 & R118 reservered for disable USB3.0
HSIC Interface is not used
Connect HSIC_CAL to GND following Qualcomm's suggestion
Place R107 close to MSM8974
within 5mm. Keep SDC1 and SDC2 trace lengths
less than 50mm and length matching within 1mm.
NC Rev.H
R107
A 33 ohm termination resistor on SDC1_CLK
is recommended for eMMC4.5 HS200.
Use a 24 ohm 1% resistor for eMMC5.0 HS400

NOTE: VDD_QFPROM_PRG needs to be at typical 1.9V
when blowing fuses. VREG_L12 regulator will be set
to 1.9V for the fuse blow duration only.
For other use cases, it will be set to 1.8V typical.
Please make sure any 3rd party IC powered by VREG_L12
can tolerate a max VDD of 1.98V.
Note:R503/R505/R508/R510 is jumper for current
measurement, would be deleted at product board.

NOTE: A 5K ohm resistor is required in parallel with C3789
as a workaround for issue 3 as mentioned in
PM8941 DRG (80-NA555-4)
R1004 R1005 are working with Lenovo standard battery
which bond inner
NOTE: QCT platform uses battery FET Rds,on as sense resistor
for BMS. Customers can use external sense resistor if required.
If external sense resistor is not used, BMS_CSP and
BMS_CSM must be tied to VBAT of PMIC.
Battery Connector
D1001 D1002 place near battery connector
R1008 place near battery connector
Remove R1008 at EVT when no issue is found.
VBATT_SENSE_M
VBATT_SENSE_P
BAT_ID is not conneted from battery to PMIC
MAX17058X+T10 is from K860 design
Pay attention on layout
battery need ID pin!
It is recommended to connect
pin 185 of PM8941 to GND
directly using a dedicated via.
