OPERATIO
The LTC4065 is a linear battery charger designed primarily
for charging single cell lithium-ion batteries. Featuring an
internal P-channel power MOSFET, the charger uses a
constant-current/constant-voltage charge algorithm with
programmable current. Charge current can be programmed
up to 750mA with a final float voltage accuracy of ± 0.6%.
The CHRG open-drain status output indicates if C/10 has
been reached. No blocking diode or external sense resistor
is required; thus, the basic charger circuit requires only
two external components. The ACPR pin (LTC4065A)
monitors the status of the input voltage with an open-drain
output. An internal termination timer and trickle charge
low-battery conditioning adhere to battery manufacturer
safety guidelines. Furthermore, the LTC4065 is capable of
operating from a USB power source.
An internal thermal limit reduces the programmed charge
current if the die temperature attempts to rise above a
preset value of approximately 115 ° C. This feature protects
the LTC4065 from excessive temperature and allows the
user to push the limits of the power handling capability of
a given circuit board without risk of damaging the LTC4065
or external components. Another benefit of the LTC4065
thermal limit is that charge current can be set according to
4065fb
