The TLV4961-3M from Infineon is a Hall-effect latch switch in a surface-mount package, designed for position and speed sensing in industrial and automotive environments. The latch switches on when a south-pole field exceeds 7.5 mT and releases at -7.5 mT (north pole), giving a clean digital output with hysteresis that rejects chatter near the threshold.
Switching thresholds and supply fit
The 7.5 mT operate point and -7.5 mT release define a 15 mT hysteresis band — wide enough to ignore magnetic noise from nearby motors or solenoids. At 2.5 mA supply current typical, the TLV4961-3M adds negligible load to a battery or regulated rail, making it a fit for power-sensitive designs.
the part is a standard surface-mount Hall switch without a known pin-compatible second source in the same family. For BOM planning, the Active status means no immediate end-of-life risk, but single-source exposure should be noted.
