Name
Pin description

I
ISEL
Switches between high power USB (IUSB up to 500 mA) and low
power USB (IUSB/5) in USB mode. A low level sets the L6924U in
low power mode and a high level sets the L6924U in high power
mode. When the AC mode is selected, the ISEL pin must be
connected to ground or left floating.
10
I
VOSNS
Output voltage sense pin.
It senses the battery voltage to control the voltage regulation loop.
11
O
VOUT
Output pin. (connected to the battery)
12
O
VREF
External reference voltage pin. (reference voltage is 1.8 V ± 2 %)
13
I/O
IEND
Charge termination pin.
A resistor connected from this pin to GND sets the charge
termination current threshold IENDTH: if ICHG < IENDTH, the charge
process ends. The voltage across the resistor is proportional to the
current delivered to the battery (gas gauge function).
14
I
MODE
Selects pin AC adapter or USB port input modes. A high level sets
the L6924U in USB mode while a low level sets the L6924U in the
AC adapter mode. When the AC adapter input is selected, the ISEL
pin status does not affect the current set.
15
I
IUSB
Charge current program pin in USB mode: a resistor connected
from this pin to ground sets the fast charge current value (IUSB up to
500 mA) with an accuracy of 7 %. The USB high power/low power
mode is selected with the ISEL pin.
16
I
IAC
Charge current program pin in AC mode: a resistor connected from
this pin to GND sets the fast charge current value (IAC up to 1 A)
with an accuracy of 7 %.
