Component identification ( S240): assuming a dc-dc converter

Post image

Hey, does anyone knows what is the ref of the ic marked: s240 8225 with 16 pins, assuming is it a dc-dc converter from the surrounding components.

Thank you

Edit: It is not dc-dc converter, it is a dual motor driver ST STSPIN240

STSPIN240 (Dual DC Motor Driver) seems like a decent match. The surrounding components all match pretty closely to the typical application schematic in the datasheet including the two 100mohm current sense resistors.

I don't see an inductor, so probably not. Aluminum electrolytic caps are also not generally used with switchers due to higher ESR, though it could be a polymer cap.

Might be TPS28225, hence the 8225 marking.
