Tiny 6-Lead (2mm

2mm) DFN Package

The LTC

4065 is a complete constant-current/constant-

voltage linear charger for single-cell lithium-ion batteries.

Its 2mm

2mm DFN package and low external component

count make the LTC4065 especially well-suited for por-

table applications. Furthermore, LTC4065 is specifically

designed to work within USB power specifications.

The CHRG pin indicates when charge current has dropped

to ten percent of its programmed value (C/10). An internal

timer terminates charging according to battery manufac-

turer specifications.

No external sense resistor or blocking diode is required

due to the internal MOSFET architecture. Thermal feed-

back regulates charge current to limit the die temperature

during high power operation or high ambient temperature

conditions.

When the input supply (wall adapter or USB supply) is

removed, the LTC4065 automatically enters a low current

state, dropping battery drain current to less than 1µA. With

power applied, LTC4065 can be put into shutdown mode,

reducing the supply current to less than 20µA.

The full-featured LTC4065 also includes automatic re-

charge, low-battery charge conditioning (trickle charg-

ing), soft-start (to limit inrush current) and an open-drain

status pin to indicate the presence of an adequate input

voltage (LTC4065A only).

The LTC4065 is available in a tiny 6-lead, low profile

(0.75mm) 2mm

2mm DFN package.
