I'm trying to figure out what this chip is. The markings are too small for me to take a picture. The info I've been able to gather is the following:

1. Packaging: it looks like WQFN (perhaps 20 pins???)
2. Markings: 8524 C3H OEB22 (the 8 could be a B; the O could be a D; the first 2 could be a Z)
3. The letters X and Y are printed on the PCB next to the chip

Thanks for the help.
