CHARGER ISL6251A – Charging IC

DCIN – The DCIN pin is the input of the internal 5V LDO.

VREF is a 2.39V reference output pin. It is internally
compensated.

VDD is an internal LDO output to supply IC analog circuit.

ACSET is an AC adapter detection input.

 

ACPRN Open-drain output signals AC adapter is present. ACPRN pulls low when ACSET is higher than 1.26V; and pulled high when ACSET is lower than 1.26V.

ICM is the adapter current output. The output of this pin produces a voltage proportional to the adapter current.

 

KBC Controller KB3926 U9

RSMRST# pin95 must drop down when power button its press. voltage equal to power button voltage.

SUSON – Suspended power on. SIO-KB3926 releases SUSON after power button its press.
