MAXREFDES1214
Reference Guide
描述
The MAXREFDES1214 is a portable USB charger that
uses a lithium-ion (Li+) battery to charge a USB device
from a USB Standard-A connector. The battery can be
charged through Micro-USB. The MAXREFDES1214 is
compliant with USB Battery Charger (BC) revision 1.2
on both USB ports. It has dynamic charger detection to
automatically set the maximum charge current allowed
to the battery based on the source’s capability. It also
features a USB adapter emulator that supports Apple®
1A charging in addition to devices that are compliant with
USB BC 1.2. For added flexibility, an I2C bus provides
fault monitoring and shutdown capability for the buckboost
regulator.
Key Features
- Battery Charger Input Current up to 1A
- USB Standard-A Output Current up to 1.5A
- 4400mAh Li+ Battery
- Thermal and Overcurrent Protection on the USB Standard-A Output
- I2C Headers for Flexible Logic Levels from 1.8V to 5.0V
- Orange LED to Indicate if the Battery Is Charging
- No External Reverse Blocking Diode Required Between Battery and Charger
