Connect to the negative supply voltage.
Provides a regulated and programmable pulsed current for the infrared emitter
diode.
Connect to the positive supply or battery voltage.
This input is used to invoke Test modes and the Timer mode. This input has an
internal pull-down.
Test input for test and programming modes. This input has an internal pull-down.
Connect to the anode of the photo diode.
Connect to the cathode of the photo diode.
Open drain NMOS output, used to drive a visible LED. This pin provides load current
for the low battery test, and is a visual indicator for Alarm and Hush modes.
Open drain NMOS output used to drive a visible LED to provide visual indication of
an Alarm Memory condition.
Usually connected to the feedback electrode through a current limiting resistor. If not
used, this pin must be connected to V
Used to charge and monitor the IRED capacitor.
This bidirectional pin provides the capability to interconnect many detectors in a
single system. This pin has an internal pull-down device and a charge dump device.
This pin is connected to the metal electrode of a piezoelectric transducer.
This pin is a complementary output to HB, connected to the ceramic electrode of the
piezoelectric transducer.
Boosted voltage produced by DC-DC converter.
Open drain NMOS output, used to drive the boost converter inductor. The inductor
should be connected from this pin to the positive supply through a low resistance
path.
