40-V, 50-mΩ, 1-ch automotive smart high-side switch with adjustable current limit

The

TPS1HB50-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 a reliable current limit, which, depending on device

variant, is adjustable from 2 A to 18 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 of load

profiles.

The

TPS1HB50-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

TPS1HB50-Q1 is available in a HTSSOP package

which allows for reduced PCB footprint.
