TPS1HB16-Q1 Automotive Smart High-Side Switch Texas Instruments TPS1HB16-Q1 Automotive Smart High-Side Switch is intended for use in 12V 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 4.4A to 49A. 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 currents. The device is capable of reliably driving a wide range of load profiles.
