See 4.13 6GND - - - Ground 7 VREFp O - I Positive microphone supply voltage 8 MICp I - I Positive microphone input 9 MICn I - I Negative handset microphone input 10 MICh I - I Headset microphone input with fixed input protection 11 VREFm - - - Negative microphone reference (star point), connect to GND. 12 LSRp O - O Positive loudspeaker output 13 LSRn O - O Negative loudspeaker output 14 GND - - - Ground 15 P3[3] IO 8 I I/O Port 16 P1[0] IO 2 I-PU I/O Port 17 SOCp I - I Battery state of charge positive input. Connect to GND if not used. See 4.9 18 SOCn I - I Battery state of charge negative input. Star point connected to the SOC resistor. Connect to GND if not used. See 4.9 19 DC_SENSE I I Voltage sense input. Connect to GND if not used. 20 DC_I I I Current sense input of DC/DC converter. Connect to GND if not used 21 DC_CTRL O 2 O-0 Switching clock for the DC/DC converter. 22 CHARGE_CTRL O 1 O-0 Charge control pin. Leave unconnected if not used. See 4.9 23 CHARGE I - I-PD (270k fixed pull- down) Charger connected indication. Switches on the device if voltage > 1.5 V. Must be connected to charger via resistor R > (Vcharger_max-3 V)/10 mA (round to next largest value in range). See 4.9 24 PAOUTp IO 500 O-0 (5k fixed pull- down) CLASSD loudspeaker positive outputs 25 VDDPA I - - CLASSD Audio Amplifier supply voltage up to 3.45 V. GND or leave unconnected if CLASSD Audio Amplifier is not used. 26 CP_VOUT1 O - I Charge Pump Output 1. A capacitor of 1 F to GND is internally connected to this pin. 27 PAOUTn IO 500 O-0 (5k fixed pull- down) CLASSD loudspeaker positive output 28 GND - - - Ground |
