DESCRIPTION
Standalone USB
Li-Ion/Polymer Battery
Charger in 2mm × 2mm DFN
The LTC
4095 is a complete constant-current/constant-
voltage linear charger for single-cell lithium-ion/polymer
batteries. Its small 2mm × 2mm DFN package and low
external component count make the LTC4095 especially
well-suited for portable USB power applications.
Up to 950mA of charge current may be programmed via a
single resistor from the PROG pin to ground. The HPWR
pin allows the charge current to be set at 20% or 100% of
its full-scale programmed value. An internal safety timer
terminates charge current. The nal oat voltage is preset
to 4.2V and held to a tight 0.5% tolerance. Also featured
is an NTC thermistor input to monitor battery temperature
while charging, a C/10 current detection output, automatic
recharge, bad-battery detection and low-battery trickle
charge. A thermal feedback loop regulates the charge
current to limit the die temperature during high power
operation or high ambient thermal conditions.
The LTC4095 is available in a tiny, low prole (0.75mm)
8-lead 2mm × 2mm DFN package.
