TPS1HB16-Q1 Automotive Smart High-Side Switch

Texas Instruments' 40 V, 16 mΩ single-channel switch features an adjustable current limit

Image of Texas Instruments' TPS1HB16-Q1 Automotive Smart High-Side SwitchTexas Instruments' TPS1HB16-Q1 is a smart high-side switch that is designed for 12 V automotive systems. The device integrates robust protection and diagnostic features to ensure output port protection even during harmful events such as short circuits in automotive systems. The switch protects against faults through a reliable current limit, which is adjustable from 4.4 A to 49 A depending on the device variant. 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.

This switch can reliably drive a wide range of load profiles. The TPS1HB16-Q1 provides a high-accuracy analog current-sense that allows for improved load diagnostics. By reporting load-current and the device temperature to a system microcontroller (MCU), the device enables predictive maintenance and load diagnostics that improve system lifetime. The TPS1HB16-Q1 is available in an HTSSOP package allowing for a reduced PCB footprint.
