Lithium-Ion Linear Battery
Charger with Thermistor Interface
The LTC
4050-4.1/LTC4050-4.2 are complete standalone
constant-current/constant-voltage linear charge control-
lers for lithium-ion (Li-Ion) batteries. Charge current is
programmable and final float voltage has
±1% accuracy.
When the input supply is removed, the LTC4050 automati-
cally enters a low quiescent current sleep mode, dropping
the battery drain current to 5
A. An internal comparator
detects the near-end-of-charge (C/10) condition while a
programmable timer, using an external capacitor, sets the
total charge time. Fully discharged cells are automatically
trickle charged at 10% of the programmed current until
cell voltage exceeds 2.49V. The thermistor interface
suspends charging if the cell temperature is outside of a
0
°C to 50°C temperature window.
The LTC4050 begins a new charge cycle when a discharged
battery is connected to the charger or when the input power
is applied. In addition, a new charge cycle is automatically
started if the battery remains connected to the charger and
the cell voltage drops below 3.88V for 4.1V cells or below
3.98V for 4.2V cells.
The LTC4050 is available in the 10-pin MSOP package.
