Identifying ICs on a ebook reader board

[chamod]

I was bored and took apart my ebook reader and took a look at the PCB. I identified most of the components, except for couple of ICs. It'd be great if someone can point me how to identify them.
The QFN16 was close to the E-Ink screen connector. Other one was close to MicroSD adaptor and NN1001 optical touch sensor controller.

P.S. - I'm not attempting to repair or anything. (It is not broken). I just looked at the components and the data-sheets to get an idea about the design.

Thanks

The QFN16 is a BQ24074.

The QFN40 is... supposedly a MSP430V325 as evidenced by this link and this link, but there is no mention of any MSP430Vxxx devices on TI's website. On the other hand, they obviously exist and there are many other models, some with "interesting" descriptions...

Thanks for taking time to reply . How did you identify the smaller one? Is there  any way to relate the numbers on the chip to a part number or just by experience?

Ah that makes sense. Thanks!
