Recommended Schematic
Shown is the recommended
schematic for the HBCC-0500.
Here are some construction tips.
1. Place the sensor, 2N4403, bin
resistor, and the 0.47 µF cap
close to each other to minimize
loop area.
2. If the 0.47 µF cap is tantalum,
its ESR must be used in series
with Rb to determine the
correct value for Rb.
3. A 1.0 µF ceramic cap may be
used in place of the 0.47 µF
cap.
4. Place the 0.22 µF cap attached
to pins 4 and 23 close to the
IC.
5. Use a single point ground close
to pin 23.
Options
There are four options on the
recommended schematic.
1. Output pull up resistor
2. Inverted output
3. Black state return
4. Threshold adjust
Pull Up Resistor
The 10 kΩ pull up resistor on the
standard or inverted output
transistor is optional. If the
transistor is driving a cable, the
resistor should be on the far end
of the cable.
