Product details

Unipolar Hall switch for automotive position sensing

The TLI49462KHTSA1 is a unipolar Hall-effect switch from Infineon's Automotive AEC-Q100 series, designed for magnetic field detection with a south-pole activation threshold of 19.2 mT trip and -19.2 mT release. The open-drain output switches a load up to 20 mA, making it suitable for direct interface to a microcontroller or logic input. The part operates from a 2.7 V supply, compatible with 3.3 V and 5 V logic rails. This covers under-hood and exterior automotive zones where ambient temperature swings are wide.

Infineon Technologies is the sole manufacturer.

Package and mounting consideration

The SC59 package (SOT-23 compatible footprint) is a three-lead surface-mount package. The open-drain output requires a pull-up resistor to the logic supply; the output current rating of 20 mA absolute maximum sets the minimum pull-up resistance at 2.7 V to 135 Ω. The south-pole activation means the magnetic field must be applied to the marked face of the package — confirm orientation during PCB layout.

Frequently asked questions

Is TLI49462KHTSA1 AEC-Q100 qualified?

Yes, the part is listed under the Automotive AEC-Q100 series. This qualification covers the -40°C to 125°C operating temperature range and the temperature-compensated switching performance.

Is TLI49462KHTSA1 equivalent to any other Infineon magnetic switch?

The TLI49462KHTSA1 is a specific variant within the TLI49462 family. Infineon offers other unipolar Hall switches with different trip thresholds and package options; the closest functional match would share the same supply voltage range and open-drain output. Confirm pin compatibility and threshold requirements against the BOM before substituting.
