The Allegro Microsystems A3212ELHLT is a micropower, ultra-sensitive Hall-effect switch featuring a latched digital output. Designed for low power consumption, its unique clocking scheme reduces average operating power to less than 15 μW with a 2.75 V supply.
This omnipolar sensor utilizes CMOS technology with chopper stabilization for improved stability, reducing residual offset voltage. It includes a Hall-voltage generator, small-signal amplifier, latch, and a MOSFET output. The device operates within a supply voltage range of 2.5V to 3.5V and has a wide operating temperature range from -40°C to 85°C.
The A3212ELHLT is housed in a compact SOT-23 surface-mount package, making it suitable for space-constrained applications. Its high frequency response of 340kHz and a fast response time of 45μs allow for efficient signal processing. The sensor is also compliant with AEC-Q100 automotive standards.
This Hall effect switch is ideal for various sensing applications where precise magnetic field detection is required. Its robust design and wide operating parameters make it a reliable choice for industrial and automotive environments.
