Neo-Iso™ Solid State Relay Driver with Sensing and Power Transfer

Add to Watch List

The TS13401 is a galvanically isolated 60V power FET driver with bi-directional blocking. The state of the switch and other product features are controlled by sending commands on the CLK input. The TS13401 supports several sensing modes where the switch state, load current, supply voltage and device temperature can be sampled. The digitized measurements can be read back from the device on the DATA pin when requested on the CLK pin. In addition, TS13401 supports power transfer from the system‘s AC supply to the low-voltage controller domain. The TS13401 includes several protection features. The switch will open in self protection if current exceeds the over-current limit or if the device temperature limit is exceeded. The switch will remain open until a new turn on sequence is given through CLK.
