Use 2.2uF for parallel charging(Dual Charging) and
4.7uF for single charging
Divide SPMS input GND and Connect common GND.
QCT ref schematic revB
Power net for SMB1357
147pin(SYSON)+5V Output 50mA
DO NOT SUPPORT WIPOWER
NEED TO CHECK
Connect ground from PMIC to input capacitor,
then to system ground

QMC Review 4/4
< 4-2-4-1_PMIC_PMI8994_Charger > Rev_0.3
Note: Place 301 ohm near PMI, daisy chair DP/DM connector - PMI - MSM
To the extent possible keep the diff pairs (DP/DM) buried
If CABC feature is unused,

Load 2A, Vin=3.0V, Vout=3.3V, Effi=80%, Ipeak=2.87A
HAPTICS_PWM
IF you use SMB, Change DNI->100K
It will be changed to 301 Ohm 1%
QCT ref schematic revB comment
Connect WLED_CABC pin to GND without pull-down.
Connect to PIN 183 first then AGND
QCT ref schematic revB
Connect together
Connect REF_GND and REF_BYP to
C4245 on top layer without via
Load 42mA, Vin=3.2V, Vout=25.3V, Effi=80%, Fsw=800kHz, Ipeak=750mA
* Route +0V9_VSENSE_KRAIT and REMOTE_GND_SNS as a differential
After QCT comment, I will change reset circuit(5/1)
Leave unused WLED_SINK_x pin as foating
PMI_SPON : Indicates to PM that S2B and S3B have been successfully enabled
If you don't want to control boost bypass externally when MSM is asleep, please short this pin to GND directly
If you want to control boot bypass when MSM is asleep, add 100Kohm PD with control signal
