Hi all,

I'll use bq24075 IC to charge LiPolymer battery. As you know, polymer batteries require a protection module which protects the battery from overcharging, overdischarging and short circuit condition. Does this IC supply these protections? Or, should I use a PCM additionally? Any advice?

Thanks all

    All of the "bq" chargers require a separate protector.  There may be some gas gauges that have protectors built in, but this would be clearly marked in the data sheet.

    Hi,

    Thanks for quick replying. I understand I must use a protection circuit, isn't it?  I searched ICs from li-ion protection part, and  saw they supply overvoltage protection, but I need undervoltage and short circuit protections as well because of liPolymer batteries characteristics. As inexperienced in power management area, I am waiting for your advices.

    Best regards

    Most protectors implements OV, UV and high current charge and discharge.
