STP8000/STP9000 Pinout, Pin 2

[schlupp]

Hi,

i'm not able to download attachments (yet), so sorry for this question:
Can you tell me what pin 2 (next to Gnd) does? It gives me 3,3V - is it to power accessories?

Thanks!

Pin nr: S16 next to "big pin" P2 Charger GND)
Generic Signal Name :FAC_POWER_OUT
I/O: I/O
Description: Switched Regulated Supply out

Signal Characteristics :

• Output voltage: 3V2 +- 0.064V
• This supply is off when the product is switched off. It
will be on when the product is in charge only mode or
normal mode.
• This supply is enabled by Hermes.
• This supply output is short circuit protected with fold-
back current limit (IOUT > 280mA)
• Maximum output current of 200mA (-20 to 55°C)
• Load regulation (Iout <100mA) 50mV max, 15mV typ.
• Output current under short circuit, 50mA typ.
• Output capacitance, 2uF

The side connector (RAC) pin nr9 (column 1, row5) have the same function:
Little differences are:

• Output voltage: 3V6 ±76mV for Vbat > 5.4V, no load.
• Load regulation (Iout <50mA): <140mV over full battery
operational range
• Maximum load current: 100mA (-20 to 55°C)
• Output current under short circuit: 30mA typ.
• This supply is on whenever there is a charged battery attached
to the product.
• This supply output is thermally protected & short circuit protected
with fold-back current limit
• Output capacitance: 1uF

As far as I remember, pin 2 belongs to the carkit audio in/out.
