The TPS1HB08-Q1 device is a smart high-side switch intended for use in 12V automotive systems. The device integrates robust protection and diagnostic features to establish output port protection even during harmful events like short circuits in automotive systems. The device protects against faults through a reliable current limit, which, depending on device variant, is adjustable from 6.4A to 70Aor set at 94A. The high current limit range allows for usage in loads that require large transient currents. The low current limit range provides improved protection for loads that do not require high peak current. The device can reliably drive a wide range of load profiles.

The TPS1HB08-Q1 also provides a high accuracy analog current sense that allows for improved load diagnostics. By reporting load current and device temperature to a system MCU, the device enables predictive maintenance and load diagnostics that improves the system lifetime.

The TPS1HB08-Q1 is available in a HTSSOP package which allows for reduced PCB footprint.
