APPLICATION NOTES
5.1
Standby Current Calculation
A calculation of the standby current is shown in
Table 5-1, based on the following conditions:
5.1.1
FIXED I
DD
The fixed I
DD
is the current from the constantly active
internal oscillator, bias circuit and guard amplifier.
5.1.2
SMOKE CHECK
The current draw from the smoke detection circuitry
during the 5 ms smoke check period.
5.1.3
LOW BATTERY CHECK
(UNLOADED)
The current drawn by the low battery detection circuitry
during the 10 ms unloaded low battery check period.
5.1.4
LOW BATTERY CHECK (LOADED)
The current drawn by the RLED during the 10 ms
loaded low battery check period.
5.1.5
CHAMBER TEST (SMOKE CHECK)
The current drawn by the smoke detection circuitry dur-
ing the 5 ms smoke check period, while the chamber is
pulled low.
5.1.6
CHAMBER TEST (CHAMBER LOW)
The current drawn to pull the chamber low when the
chamber test is performed.
5.1.7
END-OF-LIFE
(READING EE AND COUNTING)
The current drawn to read EOL bits from EE and then
increase by 1.
5.1.8
END-OF-LIFE (WRITING EE)
The current drawn to write EOL bits back to EE.
5.1.9
TOTAL CURRENT
The average total current drawn in Standby
V
DD
= 9V
LED current in loaded
battery check
= 10 mA
EOLEn
= 1
