Texas Instruments  PTPS2HB16BQPWPRQ1

The TPS2HB16-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 reliablecurrent limit, which, depending on device variant, is adjustable from4.1 A to 48.5 A.

The high current limit range allows for usage in loads that require large transientcurrents, while the low current limit range provides improved protection for loads that do notrequire high peak current. The device iscapable of reliably driving various loadprofiles.

The TPS2HB16-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 TPS2HB16-Q1 is availablein a HTSSOP package which allows for reduced PCB footprint.
