BQ25505: AC input source 10 - 1000mV ?

Part Number:BQ25505

Hello,

We are looking at using an energy harvest with ~1k impedance range, AC, 10’s to 1,000’s of mV but less than piezo.

So, we need AC-capable and ultra-low startup voltage.

Would you have an IC or bridge recommendation that would work?

Thank you, Keith
