Description

The TPS27SA08 device is a single-channel smart high-side switch intended for use with 24-V supply systems. The device integrates robust protection and diagnostic features to ensure output port protection even during harmful events like short circuits. The device protects against faults through a reliable current limit, which, depending on device variant, can be configured to react to an overcurrent event by either instantly turning the switch off or by regulating the output current at the set point (nominally 20 A). The TPS27SA08 device also provides a high accuracy analog current sense that allows for improved diagnostics whendriving varied load profiles. By reporting load current, device temperature, and supply voltage to a system MCU, the device enables predictive maintenance and load diagnostics that lengthen the system lifetime. The TPS27SA08 device is available in a small 16-pin HTSSOP package which allows for reduced PCB footprint.
