It switches on when a south-pole field exceeds 7.3 mT and releases at -7.3 mT, with temperature-compensated thresholds to maintain accuracy across the -40°C to 170°C junction range. The open-drain output sinks up to 25 mA, making it a direct fit for 3 V logic interfaces in brushless DC motor commutation, speed sensing, or valve position feedback. ## Sensing thresholds and temperature range The latch's 7.3 mT operate point and -7.3 mT release point give a 14.6 mT hysteresis band, preventing output chatter near the switch threshold. The 170°C junction rating means this part can sit next to a motor winding or exhaust valve without derating — a spec that separates it from commercial-grade Hall switches that top out at 85°C or 125°C. Supply voltage is 3 V nominal, and the output current limit of 25 mA is enough to drive a microcontroller GPIO or a small relay coil through an external transistor. The 2.5 mA switching current draw keeps the thermal budget low in dense PCB layouts. ## Sourcing and lifecycle status The SOT23-3 package is widely available in Tape & Reel or Cut Tape formats, and the part is sourced to order against your BOM quantity.","metaTitle":"TLE49612MXTSA1 Infineon Hall Latch SOT23-3 AEC-Q100","metaDescription":"TLE49612MXTSA1 Infineon Hall-effect latch, SOT23-3, 3 V supply, 7.3 mT trip point, -40°C to 170°C junction, AEC-Q100 qualified.
