Description
Factory Test pin
I
*Connect to VSS.
-
Connect to the - terminal of the battery.
-
Connect to the + terminal of the battery.
Alert indication. An active low output used to indicate specified condition thresholds have been met.
O
*When you do not use an alert function, please connect with VSS. (Note 3)
O
Battery temperature reading control pin (Note.1)
I
Battery temperature analog voltage input pin (Note.2)
I/O I2C data pin
I/O I2C clock pin
-
Not used pin. *Recommend to connect to VSS.
-
Exposed Pad, must not be connected.
(Note 1)
This pin provides power for the thermistor and goes high during a temperature read operation from Command code
x08.
(Note 2)
If TSENSE is not used leave leads TSW and TSENSE disconnected, as in figure 4 and set bit 0 of command code
register x16 low.
If TSENSE is utilized connect as in figure 5 with resistor network and set bit 0 of command code register x16 high.
(Note 3)
ALARMB indicates a low RSOC, or an under voltage battery.
No.A2237-4/13
