MSM6545/6575/6545L/6575L
Internal
status
The battery level VSS1 is applied
to the input of the constant voltage circuit.
Operating
range
–0.9 to –1.75 V
Current
1.5 mA*
consumption
Feature
When the battery level is powered down, the
internal circuit is powered directly by the
battery.
* When the software duty is about 5%
Internal
status
A doubled level of VSS2 is applied to the input
of the constant voltage circuit.
Operating
range
–0.9 to –1.75 V
Current
3 mA*
consumption
Feature
When the battery level is powered down, a
larger operating voltage margin is gained,
compared to the case of Figure 1.
* When the software duty is about 5%
Internal
status
The battery level VSS2 is applied to the input
of the constant voltage circuit.
Operating
range
–0.9 to –3.5 V
Current
1.5 mA*
consumption
Feature
When the battery level is powered down, the
internal circuit is powered directly by the
battery.
* When the software duty is about 5%
