Product details

High-side switch for 12V and 24V automotive loads

The 1 Ohm typical Rds(on) at 1A continuous output sets the conduction loss floor — at 1A the dissipation is roughly 1W, which the 8-HVSSOP exposed-pad package must sink to the board copper.

Protection and control features for harsh environments

Fixed current limiting and over-temperature fault protection are integrated, so the switch survives a shorted load or stalled solenoid without external clamp circuitry. The slew-rate controlled turn-on reduces EMI coupling into the vehicle harness. The input is non-inverting with a simple On/Off interface — no Vcc supply rail is required, which simplifies the gate drive in systems where the MCU GPIO directly controls the switch.

Frequently asked questions

Is TPS1H000AQDGNRQ1 suitable for 12V automotive systems?

Yes. The load voltage range of 4V to 40V covers 12V nominal automotive systems, and the AEC-Q100 qualification confirms it meets automotive reliability requirements.

What is the typical Rds(on) of TPS1H000AQDGNRQ1?

The typical Rds(on) is 1 Ohm. This value is specified at 25°C; actual on-resistance increases with junction temperature, so thermal design should account for the higher resistance at the 125°C operating limit.
