1 / 17 page Datasheet ○ Product structure:Silicon monolithic integrated circuit ○This product is not designed protection against radioactive rays . 1/14 TSZ02201-0Q1Q0AJ00130-1-2 © 2012 ROHM Co., Ltd. All rights reserved. 2.AUG.2012 Rev.001 TSZ22111・14・001 www.rohm.com For 2Cell Solar, Synchronous Switch-Mode Charger IC BU1840AMUV ● General Description 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. 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. 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 ● Features Synchronous Switch-Mode Charger for 2Cell Solar 400mA@Battery=3.7V,VIN=1V MPPT control voltage range:0.7V~1.5V Charging current completion voltage: 5.0V (hysteresis: 0.075V) Built in MPPT Switching frequency (160kHz,320kHz) Charging current monitor by I2C UVLO-detect Voltage:0.625V UVLO-release Voltage:0.700V Thermal Shutdown 24 pin VQFN024V4040 (4.1mm×4.1mm<MAX>) ● Typical Application Circuit(s) <For 2 Cells Solar> ● Applications Solar mobile phone Solar audio Solar portable charger Solar LED illumination ● Package(s) W(Typ.) x D(Typ.) x H(Max.) VQFN024V4040 4.00mm x 4.00mm x 1.00mm ● Typical Performance characteristics <Efficiency (for 2 cells solar)> (VINMON=1.0V, OUTS=3.7V, Pin = 50mW ~ 2W) VQFN024V4040 70 80 90 100 10 100 1000 10000 Pin [mW] SEL=GND SEL=VIN |
