USB Power Manager
with OVP and
Li-Ion/Polymer Charger
The LTC4067 is a USB power management and Li-Ion/
Polymer battery charger designed for portable battery
powered applications. The part controls total current used
by the USB peripheral for operation and battery charging.
The total input current may be left unregulated, or it may
be limited to 20% or 100% of the programmed value up
to 1.5A (typically 500mA). Battery charge current is au-
tomatically reduced such that the sum of the load current
and the charge current does not exceed the programmed
input current.
With the addition of an external P-channel MOSFET the
LTC4067 can withstand voltages up to 13V.
The LTC4067 includes a complete constant current/con-
stant voltage linear charger for single cell Li-Ion batteries.
The oat voltage applied to the battery is held to a tight
0.4% tolerance, and charge current is programmed using
an external resistor to ground. An end-of-charge status
output, CHRG, indicates full charge. Also featured is an
NTC thermistor input used to monitor battery temperature
while charging.
The LTC4067 is available in a 12-lead low prole 4mm ×
3mm DFN package.
