Highly Integrated, Linear Battery Charger with
Thermal Regulation for Portable Applications

Maxim Integrated
Figure 11 shows a circuit that adds temperature protec-
tion to the battery. Install the thermistor as close to the
battery as possible to ensure accurate temperature mea-
surement. The output of this circuit is logic high when the
battery temperature is less than 0°C and greater than
+50°C. Driving CHGEN high disables the charger.
Layout and Bypassing
Connect IN and INP together as close to the device as
possible and bypass with a 1F ceramic capacitor.
Bypass BATT to GND with a 10F ceramic capacitor.
Provide a large copper GND plane to allow the exposed
paddle to sink heat away from the device. Connect the
battery to BATT as close to the device as possible to
provide the most accurate battery voltage sensing.
Make all high-current traces short and wide to minimize
voltage drops.
