LITHIUM-ION LINEAR BATTERY CHARGER WITH THERMAL REGULATION

Thermal Control Loop
1.
Increase the input voltage to about 6.5V, and reduce
the battery simulator power supply to around 3V.
This causes increased power dissipation, which raises
the LTC4064 junction temperature. When the junction
temperature reaches approximately 105°C, the charge
current decreases enough to maintain the junction
temperature at 105°C.
2.
Increase the battery simulator voltage or reduce the
input voltage to reduce the charger power dissipation
and allow the charge current to return to the pro-
grammed current of 1A.
