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:
TBAT = OK when the battery temperature is between 0 °C and 50 °C
When the TH pin voltage rises and exceeds the VMINTH = 50 % of VREF (900 mV typ), the
L6924U stops the charge, and indicates a fault by the status pins. The device re-starts to
Figure 17.
