LTC4054 charger IC SOT23-5 package

the LTC4054 Lithium Battery Charging IC is a linear voltage and constant current charger designed for use with single-cell lithium-ion batteries. its thin sot package and minimal external component requirements for operation make it an ideal ic for designing portable electronic devices. additionally, this ic is specifically designed to work with power sources that are compatible with usb ports. due to the internal mosfet architecture, there is no need for a sense resistor or diode block at the output of the ic. the charge voltage is stabilized at 4.2 volts, and only one external resistor can be used to set the charge current.
