Hi,
Resistor R28 is not broken. also i will check no short on optical sensor (A and K).
As per 0.6mA as typical output current. i will select load resistor value accordingly (R2- 20K)
i have use TCUT1300X01 Dual Channel Transmissive Optical Sensor with Phototransistor Outputs Ic in my Project.
at TP2 and TP19 i have given 3V supply and i will check output at TP20. But at TP20 output not observed.
Please suggest solution for the same ..
please find attached schematic file...
