It is nice to know what is going wrong when a high side switch begins to display irregular behavior. When used in automotive and industrial applications, it is important to have operation be smooth and problems easily diagnosed. With a footprint in end equipment such as servo drive control modules, mixed I/O modules, and cockpit processing units, TI’s Smart High Side Switches strive to be one step above other switches and provide features that optimize performance and the system around it. With diagnostics such as load current and device temperature measurement, high side switches can be monitored for regular operation. In a fault condition, the device can remain protected or diagnose issues such as open load, short-to-GND, loss of battery, and thermal shutdown.
