2.1
The SLIC-P (PEB 4266) operates in the following modes controlled by ternary logic signals at C1, C2 and a binary
signal at C3:
Table 2
C1
1) No ‘Overtemp’ signaling possible via pin C1 if C1 is low.
2) When used with the DuSLIC
3) SLIC-P Version 1.2 features selectable current limitation (60 mA or 90 mA) in the Active and Ringing operating modes. In
