LTC4054L-4.2 150mA Standalone Linear Li-Ion Battery Charger in ThinSOT DESCRIPTIO
The LTC®4054L is a plete, constant-current/constantvoltage linear charger for single cell lithium-ion batteries. Its small size and ability to regulate low charge currents make the LTC4054L especially well-suited for portable applications using low capacity rechargeable lithium-ion coin cells. Furthermore, the LTC4054L is specifically designed to work within USB power specifications. No external sense resistor is needed, and no blocking diode is required due to the internal MOSFET architecture. Thermal feedback regulates the charge current to eliminate thermal overdesign. The charge...
