NTCER
:
When Temperature Compensation Short occurs, the output will
shut down and the LED indicator will turn red. The charger will
automatically restart after the Temperature Compensation
Short condition is removed.
BTNC
:
When there is no battery detected, the charger stops charging
the battery and the LED indicator turns red. The charger needs
to re-power on to re-start charging the battery.
CCTOF
:
When timeout arises in the Constant Current stage, the charger
stops charging the battery and the LED indicator turns red. The
charger needs to re-power on or remote on/off to re-start
charging the battery.
CVTOF
:
When timeout arises in the Constant Voltage stage, the charger
stops charging the battery and the LED indicator turns red. The
charger needs to re-power on or remote on/off to re-start
charging the battery.
FVTOF
:
When timeout arises in the Float stage, the charger stops
charging the battery and the LED indicator turns green. This
charging flow is finished; the charger needs to re-power on or
remote on/off to start charging a different battery.

Linear Format Data Bytes
The Mode bits are set to 000b.
The Voltage, in volts, is calculated from the equation:

N
Voltage V
=
Where:
Voltageis the parameter of interest in volts;
V is a 16 bit unsigned binary integer; and
N is a 5 bit two' complement binary integer.
