Datasheet  
For 2Cell Solar,  
Synchronous Switch-Mode Charger IC  
BU1840AMUV  
General Description  
Applications  
The BU1840AMUV device provides the best system to  
the product charged with 1cell Li-ion battery and 3cell  
Nickel-metal-hydride batteries using the 2cell, 3cell, and  
4cell solar panel.  
It is possible to boost it according to the voltage of 2 cell  
solar panel with built-in the function to boost the low  
voltage input.  
„ Solar mobile phone  
„ Solar audio  
„ Solar portable charger  
„ Solar LED illumination  
Package(s)  
W(Typ.) x D(Typ.) x H(Max.)  
4.00mm x 4.00mm x 1.00mm  
Moreover, the solar battery maximum dissipation can be  
drawn out with built-in the peak power track function. It is  
possible to select the the switching frequency according  
to the terminal SEL.  
VQFN024V4040  
It is also possible to monitor the charging current by the  
I2C interface.  
Built in heat reckless driving protection (Thermal  
shutdown), decrease voltage protection, and input  
current protection for protection function
