The widely varying environmental conditions in which SLICs operate may lead to the
chip temperature limitations being exceeded. The PBL 38630/2 SLIC reduces the DC
line current when the chip temperature reaches approximately 145 oC and increases line
current again automatically when the temperature drops. Accordingly transmission is not
lost under high ambient temperature conditions.
The detector output, DET, is forced to a logic low level when the temperature guard is
active.
