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.
Applications
• Power load/rail switching
• Input supply muxing
• Isolated power supplies
• Solid state relays
• HVAC control
