Note:
Pre-alarm output (TEA3718SFP)
When the junction temperature reaches T1° C (typically = 170 ° C) a pre-alarm signal is
generated on the PRE-ALARM output pin.
Soft thermal protection occurs when function temperature reaches T2 (T2 > T1).
Current reduction in alarm condition
The resistance values given in this section are for the V_CH threshold. They should be
adjusted when using other comparator thresholds or V_ref values.
