Description
The SMB138DSV is a programmable single-cell lithium-ion/lithium-polymer battery charger designed for portable applications. It is a high-efficiency switch-mode device that can charge high-capacity LiIon batteries via a USB or AC adapter input. The SMB138DSV provides a more efficient and simple solution than conventional linear chargers, and its buck converter architecture increases charge rate for the Li-Ion cell without causing thermal issues. The SMB138DSV also supports USB On-the-Go devices by providing the required USB-OTG +5V power supply using the Li-Ion battery as a source.
Specifications and features

Comparison
Advantages- High-efficiency switch-mode operation eliminates the thermal problems of conventional linear chargers
- Buck converter architecture effectively multiplies the input current to increase charge rate for the Li+ cell
- Supports USB On-the-Go devices by providing the required USB-OTG +5V power supply using the Li-Ion battery as a source
- High-accuracy float voltage regulation (1%) and internal power MOSFETs with precision current sensing
- Pre-charge and complete-charge (36/240min) safety timers
- Digital programming of all major parameters via I2C interface
Disadvantages- Only suitable for single-cell lithium-ion/lithium-polymer batteries
- Lead-free package may be less durable than leaded packages
- Not suitable for devices requiring more than 1.25A continuous charging current from AC adapter
