AZC SPECIFICATIONS (CONTINUED)
Min Typ Max
AZC current limit (note 1) 13.5mA 15.5mA 16.5mA
(14.5mA)
EOL & detector quiescent 11.95mA
EOL, no detectors 7.0mA 7.8mA 8.2mA
(7.2mA)
Fault threshold 4.4mA 5.75mA 6.8mA
Detector quiescent 0mA 4.0mA
Notes
1. The minimum figures shown are for battery voltage greater than the minimum
Standby (Battery Fail) level i.e. 21.5V. The figures shown in brackets are for a
battery voltage greater than 22.5V.
2. Modes 1 & 2 have the same thresholds before the Alarm state is latched. For Mode
2 additional current is turned on once the Alarm state is latched (refer to Graph
3.4.2).
Min Typ Max
Mode 3 Only
Current into short circuit 34.3mA
Current into 800 Ohm (note 3) 14.2mA 14.8mA 15.3mA
Current into 2000 Ohm (note 4) 8.0mA 8.2mA 8.4mA
EOLR Current 2mA
Minimum current for EOLR & 2k circuit 1.64mA
Modes 3 & 4
Fault thresholds 0.85mA 1.28mA 1.59mA
Maximum allowable load or circuit leakage 0.5mA
Notes
3. I.e. short at end of an 800 Ohm circuit (gives voltage band B2 alarm, ref graph 3.4.1).
4. I.e. short at end of a 2000 ohm circuit (gives voltage band B3 alarm, ref graph 3.4.1).
MCP Zener Diode
For voltage band B3 operation BZT03C15 3W, 15V.
