Description
The TS13101 is a galvanically isolated 60V power switch device with bi-directional blocking. The device includes a single integrated 110mOhm high voltage FET allowing high efficiency switching of power loads or other high current applications. The input pin, CLK, controls the turn on/off of the switch. When the correct CLK sequence is provided the switch will latch on and stay on until the turn off sequence is given or a fault is detected. The TS13101 includes several protection features. Each FET has an integrated over-current shut-down to prevent device damage during short-circuit or other unusually high load conditions. If an over-current event is detected for a time the FET is latched off until the CLK turn off sequence is given. While the CLK pin is active after an over-current event or in the event of an incorrect turn-on sequence, the DATA pin is toggled at ¼ the CLK frequency.
