The Texas Instruments HSS-MOTHERBOARDEVM helps designers evaluate the operation and performance of the TPS27SA08, TPS1HA08-Q1, TPS2HB08-Q1, TPS2HB16-Q1, TPS2HB35-Q1 and TPS2HB50-Q1 devices.

These devices are fully-protected high-side switches, with an integrated NMOS power FET, and charge pump. Full diagnostics and high-accuracy current sense features enable intelligent control of the load.

The device diagnostic reporting supports load current status and device temperature on an analog sense output pin SNS. The SNS pin sources a current proportional to the selected parameter. By adding a pulldown resistor on the SNS pin, the developed voltage is proportional to the selected parameter as well. The diagnostics can be disabled for multiplexing the sense pin between different devices.
