Add To BomA3212ELHLT-T General Description
The A3212ELHLT-T is a Hall-effect sensor manufactured by Allegro Microsystems. It is designed for high-temperature applications, operating up to 150°C. The sensor features a quiescent output voltage of 50% of the supply voltage, with increased sensitivity provided by a chopper stabilization technique. It has a wide operating voltage range of 3 V to 24 V, making it ideal for various automotive and industrial applications.The A3212ELHLT-T sensor also offers enhanced ESD protection, with a minimum rating of 6 kV (HBM) ensuring reliable operation in harsh environments. It features a single open-drain output that switches low with a south magnetic field and high with a north magnetic field. The sensor has a response time of less than 2.5 ms, providing fast and accurate detection of magnetic fields.Additionally, the A3212ELHLT-T is available in a small SOT-23 surface-mount package, making it easy to integrate into existing designs. It is RoHS-compliant and has a Pb-free lead finish, making it environmentally friendly.
