TPS1H000AQDGNRQ1 High-Side Switch | 40V/1Ω | Adjustable Current Limit | HVSSOP-8 Package | Texas Instruments Automotive Grade

The TPS1H000AQDGNRQ1 is a fully protected automotive-grade single-channel smart high-side power switch from Texas Instruments (TI), integrating a 1000mΩ NMOS power FET. It supports a wide operating voltage range of 3.4V to 40V and features adjustable current limit via an external resistor (±10% accuracy at ≥300mA), effectively limiting inrush or overload currents and simplifying front-stage power design. The device supports standalone operation (no MCU required), configurable behavior after current limit (hold/latch/auto-retry modes), and comprehensive diagnostics—including open-load detection in both ON and OFF states. With standby current below 500nA, it is housed in an 8-HVSSOP package and is AEC-Q100 Grade 1 qualified (-40°C to +125°C), making it ideal for automotive body lighting, ADAS sensors, relay drivers, and general resistive/inductive/capacitive loads. We supply 100% original, new products with fast delivery and professional technical support.
