Application information: monitoring and protection L6924U
24/37 Doc ID 14716 Rev 2
When the voltage (and thus, the temperature), returns to the window range, the device re-
starts the charging process. Moreover, there is a hysteresis for both the upper and lower
thresholds, as shown in
Figure 18.
Note: T
BAT
= OK when the battery temperature is between 0 °C and 50 °C
When the TH pin voltage rises and exceeds the V
MINTH
= 50 % of V
REF
(900 mV typ), the
L6924U stops the charge, and indicates a fault by the status pins. The device re-starts to
