The TPS2HB50-Q1 device is adual-channel smart high-side switch intended for use in 12-V automotive systems. The deviceintegrates robust protection and diagnostic features to ensure output port protection even duringharmful events like short circuits in automotive systems. The device protects against faultsthrough a reliable currentlimit, which, depending on device variant, is adjustable from1.6 A to 18 A. The high currentlimit range allows for usage in loads that require large transient currents, while the low currentlimit range provides improved protection for loads that do not require high peak current.The device is capable of reliably driving variousload profiles.

The TPS2HB50-Q1 also providesa high accuracy analog current sense that allows for improved load diagnostics. By reporting loadcurrent and device temperature to a system MCU, the device enables predictive maintenance and loaddiagnostics that improves the system lifetime.

The TPS2HB50-Q1 is availablein a HTSSOP package which allows for reduced PCB footprint.
