LTC4065/LTC4065A
APPLICATIO S I FOR ATIO
Furthermore, the voltage at the PROG pin will change
proportionally with the charge current as discussed in the
Programming Charge Current section.
It is important to remember that LTC4065/LTC4065A
applications do not need to be designed for worst-case
thermal conditions since the IC will automatically reduce
power dissipation when the junction temperature reaches
approximately 115 ° C.
Board Layout Considerations
In order to deliver maximum charge current under all
conditions, it is critical that the exposed metal pad on the
backside of the LTC4065/LTC4065A package is soldered
to the PC board ground. Correctly soldered to a 2500mm 2
double-sided 1 oz. copper board the LTC4065/LTC4065A
has a thermal resistance of approximately 60 ° C/W. Failure
backside of the package and the copper board will result
in thermal resistances far greater than 60 ° C/W. As an
example, a correctly soldered LTC4065/LTC4065A can
deliver over 750mA to a battery from a 5V supply at room
temperature. Without a backside thermal connection, this
number could drop to less than 500mA.
V CC Bypass Capacitor
Many types of capacitors can be used for input bypassing;
however, caution must be exercised when using multi-
layer ceramic capacitors. Because of the self-resonant and
high Q characteristics of some types of ceramic capaci-
tors, high voltage transients can be generated under some
start-up conditions, such as connecting the charger input
to a live power source. For more information, refer to
Application Note 88.
