• Manufacturer Part Number: EPC110
• Description: Fully integrated configurable light barrier driver & receiver
• Manufacturer: EPC [Espros Photonics corp]

High speed detection rate design (refer also to datasheet epc112)
Figure 20 shows the epc 110 as an example in a high speed detection rate light barrier application with minimal part count. This design is
optimized for a fast reading of light beam interruptions. Where as the working principle is similar to the above example. This driver circuit
operates with a VDD
Notice:
The schematic is for illustrating the basic circuit idea only. For the real built up the designer has to take all other additional influence factors in
consideration too e.g. design rules, power rating, heat dissipation, ...
The following table shows the parameter allocation in the memory:
Parameter settings can be done by writing complete 16 bit registers only.
