36-V, 8-mΩ, 10-A, 1-ch automotive smart high-side switch with current monitoring

The TPS27SA08-Q1 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 react to an overcurrent event by regulating the output current at the set point (nominally 20 A). The TPS27SA08-Q1 device also provides a high accuracy analog current sense that allows for improved diagnostics when driving 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-Q1 device is available in a small 16-pin HTSSOP package which allows for reduced PCB footprint.
