Does anybody know this chip? It gets input from a photo-resistor and triggers a solar light circuit.

The part is probably an MMBT5551 160V NPN BJT.
The part appears to be a BC846BPN: https://assets.nexperia.com/documents/data-sheet/BC846BPN.pdf It is a NPN/PNP transistor pair. Page 2 shows part marking is 'PJ' with 't' indicating made in Malaysia.

Hello Every body again!!! Thank you everybody for your support and comments!!! Finlay I found out what this chip is !! The chip is connected to photo-resistor and a regulator (MT3608 / B6288). After some research I realized that similar circuits uses this kind of connections and components in which the photo-resistor always in connected to the first chip ,which is the one with the 5 pins and in all the other similar circuits they use the same connection! After that I search what kind of chip is the one in the similar circuits and I found out that the commonly use a single inverter gate in order to activate the next stage of the circuit when there is no light. It must be something similar to the following link:

and (A) pin 2 is the input from photo-resistor and the output is (Y) pin 4. The same like the photo of the circuit. I have not find the exact type of this LA..4 chip but it must be something like the one in the pdf. Thanks everybody for the support !!!!
