STMicroelectronics VNI4140KTR-32 High Side 8, High Side Power Switch IC 24-Pin, PowerSSO-24

The STMicroelectronics solid state relay, it is a monolithic device designed using VIPower technology. In an overload condition overheats and turns OFF and back ON automatically in order to maintain its junction temperature between TTSD and TR. If this condition makes case temperature reach TCSD, the overloaded channel is turned OFF and restarts only when case temperature has decreased down to TCR. In case of more than one channel in overload, restart of the overloaded channels is not simultaneous, in order to avoid high Peak current from the supply.

Per channel short-circuit protection
