DIAGNOSTIC MODE PIN FUNCTION

I/O
7
Disabled as an output. A high on this pin directs the photo amplifier output to pin C1 or
C2, determined by the level on VSEN. Amplification occurs during the IRED active time.
VSEN
15
If I/O is high, then this pin controls the gain capacitor that is used. If VSEN is low, the
normal gain is selected and the photo amplifier output appears on C1. If VSEN is high,
high gain is selected, and the photo amplifier output is on C2.
FEED
10
If VSEN is low, then taking this input high will enable hysteresis, which is a nominal
10% gain increase in normal gain mode.
COSC
12
If desired, this pin can be driven by an external clock.
HORNB
8
This pin becomes the smoke integrator output. A high level indicates that an alarm con-
dition has been detected.
LED
11
The LED pin is used as a low battery indicator. For VDD above the low battery thresh-
old, the open drain NMOS is off. If VDD falls below the threshold, the NMOS turns on.
