Objective specification
Battery charge level indicator
SAA1501T
Open battery protection
Open battery protection is active when V
CC
= 4.5 V (typ.).
The SAA1501T will then react as if the system is in the
standby mode. This means that the LEDs are turned off in
the LED mode, in the LCD mode the flickering is stopped
and the enable pin (EN) is switched to floating.
Testing
A user test facility is built-in for checking if the LCD and/or
LED displays are mounted correctly. Pin R
CCC
is used as
a test pin. Raising the voltage above 1 V during the set-up
time will activate the test. The test mode can only be
started in the standby mode. In the test mode all counters
are reset and will be active successively in the sequence
BLI, L20, L40, L60, L80, L100 and FULL with an interval
period determined by T
osc
. The test mode can be exited via
the following methods:
Power-on; the Coulomb counter retains the latest data
displayed.
Automatically after the test cycle time; the Coulomb
counter is reset.
