Technical Details & Description

The TLV4946K is a unipolar Hall-effect switch from Infineon, designed for position and proximity sensing in environments that see wide temperature swings — the operating range spans -40°C to 150°C. It switches on when a south-pole magnetic field exceeds 13.9 mT and releases at 5 mT, with an open-collector output that sinks up to 20 mA.

Magnetic thresholds and temperature compensation

The 13.9 mT operate point and 5 mT release give a 8.9 mT hysteresis — wide enough to reject mechanical vibration and magnetic noise in a motor-drive or valve-position application.

the surface-mount footprint suits standard reflow assembly.

Frequently asked questions

What does the 13.9 mT operate / 5 mT release mean for my magnet selection?

The 13.9 mT operate point means the Hall switch triggers when the south-pole field strength at the sensor face reaches that level. For a typical N35 neodymium magnet, that corresponds to an air gap of roughly 3–5 mm depending on magnet size. The 5 mT release gives 8.9 mT hysteresis, which prevents chatter from mechanical vibration.
