Product details

The TLV49462LXA is a south-pole-activated Hall-effect latch from Infineon. It switches its open-drain output on at 3.5 mT (typical) and releases at -3.5 mT, meaning it holds state until the opposite polarity field is applied — a true latch, not a switch. It runs from a 2.7 V supply rail and draws 6 mA typical switching current, so it fits on a 3.3 V or 5 V bus without a separate regulator. The through-hole package (Bulk) means it goes into a wave-solder process, not a reflow oven — check the hole size and wave profile before placing it.

Temperature compensation and operating range

Without this, the magnetic trip threshold would drift with temperature, causing false triggers or missed edges in outdoor or engine-bay environments.

The through-hole package (Bulk) is a standard leaded format, so supply is steady through distribution.

Frequently asked questions

Is TLV49462LXA a latch or a switch?

It is a latch (timing function listed as Latch). The output turns on at 3.5 mT (south pole) and stays on until the field reverses to -3.5 mT — it holds state, unlike a switch that resets when the field drops.

Does TLV49462LXA require an external resistor?

The output is open drain, so a pull-up resistor to the supply rail is needed for a logic-level output. The datasheet shows the typical value; the output can sink up to 20 mA.
