Semtech TS13501 | Demoboard TS13501EVM

Description

TS13501 is a bi‐directional blocking 36V power DC or AC switch device which offers galvanic isolation between the control system and load. The device includes integrated 240mΩ 36V switch allowing high efficiency switching of power loads or other high current applications. The differential input controls the state of the switch by way of a transient‐immune serialprotocol.The TS13501 includes an over‐current protection feature. Load current is monitored when the switch is in on state, notifying the system microcontroller of over‐current faults by way of the STAT status pin.
