OPERATION
The LTC4069 is a linear battery charger designed primarily An internal thermal limit reduces the programmed charge
for charging single-cell lithium-ion batteries. Featuring current if the die temperature attempts to rise above a
an internal P-channel power MOSFET, the charger uses a preset value of approximately 115°C. This feature protects
constant-current/constant-voltage charge algorithm with the LTC4069 from excessive temperature and allows the
programmable current. Charge current can be programmed user to push the limits of the power handling capability
up to 750mA with a final float voltage accuracy of ±0.6%. of a given circuit board without risk of damaging the
The CHRG open-drain status output indicates if C/10 has LTC4069 or external components. Another benefit of
been reached. No blocking diode or external sense resistor the LTC4069 thermal limit is that charge current can
is required; thus, the basic charger circuit requires only be set according to typical, not worst-case, ambient
two external components. An internal termination timer temperatures for a given application with the assurance
and trickle charge low-battery conditioning adhere to that the charger will automatically reduce the current in
battery manufacturer safety guidelines. Furthermore, the worst-case conditions.
LTC4069 is capable of operating from a USB power
source.
