+SC8906 High Efficiency, Synchronous, Buck-Boost Charger Converter with Four Integrated MOSFET
21
+
22
+SC8906 is a synchronous buck-boost charger converter.
23
+
24
+Four switches are integrated to simplify the system design.
25
+
26
+SC8906 employs current-mode control and can support very wide input and output voltage range. It can support applications from 2.7V to 22V VBUS range. It is able to effectively manage charging for 2~4 cell batteries no matter input/output voltage is higher, lower or equal to battery voltage.
27
+
28
+SC8906 supports input current limit, DPM (dynamic power management) function, and fast charging detecting. Charging voltage and current limit can be adjusted by external resistor.
29
+
30
+SC8906 supports internal current limit, under voltage protection, over voltage protection, output short protection and over temperature protections to ensure safety under abnormal conditions.
31
+
32
+The IC is in a 21 pin 4x4 QFN package
