The CXLB7386 is an integrated USB power switch with boost converter to meet USB 5V
power requirements from a 2V to 5V input supply. The features include a USB compliant
power output, output switch enable, thermal shutdown and current limit.The USB power
switch is an integrated 200mΩ power switch with current limiting protection at 1.4A.
The boost converter output is an auxiliary 3V to 5.5V output to power additional loads.
Its Load current can program by an external resistor from as low as 130mA to as high as
2000mA. It can operate in stable waveforms without external compensation.

产品概述 返回TOP
The CXLB7386 is a complete constant-current/constant-
voltage linear charger for single cell lithium-ion batteries.
Its ThinSOT package and low external component count
make the CXLB7386 ideally suited for portable applications.
Furthermore, the CXLB7386 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 limit the
die temperature during high power operation or high
ambient temperature. The charge voltage is fixed at 4.2V,
and the charge current can be programmed externally with
a single resistor. The CXLB7386 automatically terminates
the charge cycle when the charge current drops to 1/10th
the programmed value after the final float voltage is
reached.
When the input supply (wall adapter or USB supply) is
removed, the CXLB7386 automatically enters a low current
state, dropping the battery drain current to less than 2μA.
The CXLB7386 can be put into shutdown mode, reducing
the supply current to 25μA.
Other features include charge current monitor,
undervoltage lockout, automatic recharge and a status pin
to indicate charge termination and the presence of an input
voltage.
