22 CHARGE_CTRL O 1 O-0 ANALOG OUTPUT. Charge control pin. Supplied by internal VBAT
if device is off else from AVD.
Leave unconnected if not used.
23 CHARGE / P1[7] I - I-PD
(270k
fixed
pull-
down)
INPUT. Charger connected indication and supply voltage for power
management. Switches on the device if voltage > Vih_a3pad. Must
be connected to charger via resistor R>(Vcharger_max-3 V)/10 mA
(round to next largest value in range). An internal 10 ms hold circuit
keeps device on if the charger voltage ripple momentarily drop
below Vil_charge. This eliminates the use of expensive ripple filter.
If used as port pin, the maximum input switching speed of this pin is
100 kHz. Leave unconnected if not used.

OUTPUT. DIP port DP1
25 VDDPA I - - CLASSD Audio Amplifier supply voltage up to 3.45 V.
GND or leave unconnected if PAOUT/P3[1:0] ports are not used.
26 CP_VOUT1 O - I Charge Pump Output 1.
A capacitor of 1 F to GND is internally connected to this pin.

May be directly connected to VBAT. If used as port pin, the maxi-
mum input switching speed of this pin is 100 kHz.
30 ULP_XTAL I - I 32.768 kHz XTAL clock input. Connect to GND if not used. (Note 7)
31 ULP_PORT I - I Ultra Low Power Port Pin. Connect to GND if not used. (Note 7)
