The TPS2HB16-Q1 device is a dual-channel smart high-side switch intended for use in 12-V automotive systems. The device integrates robust protection and diagnostic features to ensure 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 4.1 A to 48.5 A. The TPS2HB16F-Q1 device is designed to be able to drive 2x35W, 2x27W, and 2x21W bulbs due to its high fixed current limit of 60A.

The high current limit range allows for usage in loads that require large transient currents, while the low current limit range provides improved protection for loads that do not require high peak current. The device is capable of reliably driving various load profiles.

The TPS2HB16-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 TPS2HB16-Q1 is available in a HTSSOP package which allows for reduced PCB footprint.
