Application information: monitoring and protection
The L6924D uses a VFQFPN 3mm x 3mm 16-pin package with an exposed pad that allows the
user to have a compact application and good thermal behavior at the same time. The L6924D
has a low thermal resistance because of the exposed pad (approximately 75°C/W, depending
on the board characteristics). Moreover, a built-in thermal protection feature prevents the
L6924D from having thermal issues typically present in a linear charger.
Thermal Control is implemented with a thermal loop that reduces the charge current
automatically when the junction temperature reaches approximately 120°C. This avoids further
temperature rise and keeps the junction temperature constant. This simplifies the thermal
design of the application as well as protects the device against over-temperature damage.
The figure above shows how the thermal loop acts (with the dotted lines), when the junction
temperature reaches 120°C..
