Description

The TPS1HB16-Q1 device is a 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 areliable current limit, which, depending on device variant, is adjustable from 4.4 A to 49 A. 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 a wide range ofload profiles. The TPS1HB16-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 TPS1HB16-Q1 is available in a HTSSOP package which allows for reduced PCB footprint. The TPS1HB16-Q1 device is a smart high-side switch intended for use in 12-V automotive systems.
