2 Device-Level Protection in TI High Side Switches (HSS)

The devices tested are the TPS1HC100, TPS1HC30, and TPS2HC08, which have internal protection features during a STG event that can alert users of the fault while preventing damage. The adjustable current limit allows the device to clamp the inrush current under start up and short circuit events. The current limit holds the current to a set value and pulls up the SNS pin to VSNSFH. After the fault is asserted, the device turns off after the device reaches relative or absolute thermal shutdown.
