q. Operating temperature
•
–20 to +70°C
r. Power supply voltage
OPTION A, OPTION B (1.5 V versions): 1.3 to 1.7 V
Note: The operation will only be at the battery voltage and no voltage halver circuit can be used.
OPTION C, OPTION D (3.0 V versions): 1.8 to 3.6 V
Note: It is possible to select by software to use the output of the halver circuit as the power supply
of the voltage regulator circuit when the battery voltage is in the range 2.4 to 3.6 V, and to
use the battery voltage itself as the power supply of the voltage regulator circuit when the
battery voltage is in the range 1.8 to 2.4 V.
It is possible to detect whether the battery voltage is 2.4 V or 1.8 V using the BLD function.
• When the halver circuit is ON: 2.4 to 3.6 V
• When the halver circuit is OFF: 1.8 to 2.4 V
