Galvanic Isolated Latching

60V Power Load Switch

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.
