UCS1002 Smart Bettery Charger Hardware Reference Design
The UCS1002 has advanced USB Port Power / Battery Charging features that can be employed to create unique
charging solutions. The objective of this application note is to describe a simple AC-DC charger that:
? Detects when a portable device is plugged in
? Presents various charger emulation profiles to the portable device
? Charges the portable device
? Terminates charging at a specific current level and turns off VBUS to avoid over-charging.
? Detects portable device removal and resets for the next portable device
A secondary goal is describe how to minimize power consumption when there is no portable device plugged in and after charging is complete.
