1. The TSM121 starts working properly before 14V, but the 12V line over current protection can be reliable only when Vcc has reached a
sufficient level: t(he DC supply voltage must be higher than the voltage applied on the Is12 input (12V line protection) plus 2V. For exam-
ple, if 13.2V is present on the IS12 input, the minimum required value on Vcc is 15.2V.
