TS13401 Neo-Iso Solid State Relay Driver with Sensing and Power Transfer POWER MANAGEMENT Features Description The TS13401 is a galvanically isolated 60V power FET Low Quiescent Operating Currents driver with bi-directional blocking. The state of the 15A in ON state 2mA in Sensing Mode switch and other product features are controlled by sending commands on the CLK input. Switch to controller scalable galvanic isolation Single control signal for input commands The TS13401 supports several sensing modes where Microcontroller-compatible levels the switch state, load current, supply voltage and Switch Characteristics device temperature can be sampled. The digitized Bi-directional blocking in OFF state measurements can be read back from the device on Up to 60V FETs supported the DATA pin when requested on the CLK pin. In Up to 10A current during inrush addition, TS13401 supports power transfer from the and 5A continuous operation systems AC supply to the low-voltage controller Operating Modes domain. Zero-cross ON / OFF The TS13401 includes several protection features. The Immediate ON / OFF switch will open in self protection if current exceeds Dithering Mode for system power sharing the over-current limit or if the device temperature limit Switch state polling is exceeded. The switch will remain open until a new Sensing Modes for system data acquisition turn on sequence is given through CLK.
