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 VCH threshold. They should be

adjusted when using other comparator thresholds or Vref values.
