Pin Descriptions
V
CC
Supply voltage input
SCL
Serial memory clock
This output is used to clock the data
transfer between the bq2092 and the ex-
ternal nonvolatile configuration memory.
SDA
Serial memory data and address
This bi-directional pin is used to trans-
fer address and data to and from the
bq2092 and the external configuration
memory.

LED display segment outputs
Each output may activate an external LED
to sink the current sourced from V
CC
.
V
SS
Ground
SR
Sense resistor input
The voltage drop (V
SR
) across pins SR and
V
SS
is monitored and integrated over time
to interpret charge and discharge activity.
The SR input is connected to the sense re-
sistor and the negative terminal of the
battery. V
SR
< V
SS
indicates discharge, and
V
SR
> V
SS
indicates charge. The effective
voltage drop, V
SRO
, as seen by the bq2092
is V
SR
+ V
OS
(see Table 3).
DISP
Display control input
DISP high disables the LED display. DISP
floating allows the LED display to be active
during charge if the rate is greater than
100mA. DISP low activates the display for 4
seconds.
SB
Secondary battery input
This input monitors the cell pack voltage as
a single-cell potential through a high-
impedance resistor divider network.
cell pack voltage is reported in the SBD
register function Voltage (0x09) and is com-
pared to end-of-discharge voltage and
charging voltage parameters.
The
NC
No connect
SCD
Serial communication data
This open-drain bidirectional pin is used to
transfer address and data to and from the
bq2092.
SCC
Serial communication clock
This open-drain bidirectional pin is used to
clock the data transfer to and from the
bq2092.
REF
Reference output for regulator
REF provides a reference output for an op-
tional micro-regulator.
V
OUT
Supply output
This output supplies power to the exter-
nal EEPROM configuration memory.
