Hi,
I have designed in a bq24232H to charge a single Li-Ion cell rated at 210mA by Samsung. The design is for a wearable product in the form of a wristband. What I need to find out is if the battery requires additional protection, such as the bq29703, that would provide over/under voltage & over current protection (that the bq24232H lacks) in order to pass a UL safety certification for a wearable device. The application circuit on pg. 23 & 24 shows the battery without any additional protection circuit. The battery is fully encapsulated in the wrist band, and is not accessible by the user nor is it capable of being replaced. I would appreciate any comments on the necessity for additional battery protection.
Thanks, Mike Boos
