It switches the output state when the magnetic field crosses the 2mT trip point and resets at -2mT release, giving a 4mT hysteresis window that rejects chatter near the threshold. The open-drain output can sink up to 5mA and requires an external pull-up resistor to the supply rail — a common detail when replacing a push-pull sensor. Supply voltage spans 3V to 5.5V, so it runs directly from a 3.3V or 5V rail without an extra regulator. Typical positions include transmission gear detection, camshaft/crankshaft speed sensing, and brushless-DC motor commutation where the latch holds state until the opposite pole passes the sensor. ## Sourcing and lifecycle — active, no end-of-life pressure The part is supplied in Tape & Reel (TR) or Cut Tape (CT) in the PG-SOT23 package. ## Open-drain output — pull-up resistor required Because the output is open-drain, the pin floats high only when an external resistor pulls it to VDD. Without that resistor the output never reaches a logic-high state. Typical pull-up values range from 1 kΩ to 10 kΩ depending on the bus capacitance and the 5mA current limit. The supply current max is 2.4mA, so the pull-up resistor adds to the total load on the 3V–5.5V rail. At 3.3V a 1 kΩ pull-up draws 3.3 mA when the output is low — staying within the 5mA sink limit but doubling the sensor's own draw.","metaTitle":"TLE49631MXTSA1 Infineon Hall Effect Latch Sensor –","metaDescription":"Infineon TLE49631MXTSA1 Hall effect latch, AEC-Q100, 2mT trip / -2mT release, 3V-5.5V supply, open-drain output, SOT23-3.
