SLIC-P
PEB 4266
Functional Description
2.2
Current Limitation / Overtemperature
According to the application requirements the output current limit for SLIC-P can be selected by C3 (see
Table
2).
With C3 = L, the total current delivered by the output drivers is limited to typically 90 mA in operating modes ACTL,
ACTH, ACTR, HIT and HIR. C3 = H sets this limitation to typically 60 mA in operating modes ACTL, ACTH, ACTR,
ROT and ROR.
If, however, the junction temperature exceeds 165 °C, the current limit is further reduced to keep the junction
temperature constant.

Simultaneously, pin C1 sinks a signalling current
