It operates from a 3 V supply rail and delivers an open-drain output that sinks up to 25 mA — enough to drive a logic input or a small load directly. 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. Temperature compensation keeps the trip points stable across the -40°C to 125°C range, so the switching window doesn't drift when the board heats up or the ambient drops. ## 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. The 3 V supply is compatible with 3.3 V logic families without a level shifter, though the open-drain output needs an external pull-up resistor to the host supply rail. 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. ## Lifecycle and sourcing reality 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.","metaTitle":"TLV4961-3M Hall Switch – Infineon, 3V, Latch, 7.5mT Trip","metaDescription":"Infineon TLV4961-3M Hall switch: 3V supply, open-drain output, latch with 7.5mT trip / -7.5mT release, -40 to 125°C.
