Product details

What this Hall latch does and where it fits

The TLE49612MXTSA1 is an Infineon Hall-effect latch from the Automotive AEC-Q100 series, designed for magnetic position sensing in harsh environments. It switches on when a south-pole field exceeds 7.3 mT and releases at -7.3 mT, with temperature-compensated thresholds to maintain accuracy across the -40°C to 170°C junction range.

Sensing thresholds and temperature range

The latch's 7.3 mT operate point and -7.3 mT release point give a 14.6 mT hysteresis band, preventing output chatter near the switch threshold. The 170°C junction rating means this part can sit next to a motor winding or exhaust valve without derating — a spec that separates it from commercial-grade Hall switches that top out at 85°C or 125°C.

Sourcing and lifecycle status

Frequently asked questions

Is TLE49612MXTSA1 automotive grade?

Yes, it is qualified to AEC-Q100, the automotive stress test standard for ICs. The -40°C to 170°C junction temperature range covers under-hood and transmission applications.

What is the sensing distance of TLE49612MXTSA1?

The magnetic switch points are specified at 7.3 mT operate (south pole) and -7.3 mT release. The physical distance to the magnet depends on the magnet's field strength and orientation; the datasheet provides typical air-gap curves for common magnet materials.

What is the output type of TLE49612MXTSA1?

Open-drain output. It pulls low when the south-pole field exceeds the operate threshold and goes high-impedance when the field drops below the release point. An external pull-up resistor to the supply rail is required.
