ALLEGRO MICROSYSTEMS  A3212ELHLT-T  Hall Effect Sensor, Switch, 1 mA, SOT-23, 3 Pins, 2.5 V, 3.5 V

Product Overview

The A3212ELHLT-T is a pole independent, ultrasensitive Hall Effect Switch with latched digital output. Either a north or south pole of sufficient strength will turn the output ON in the A3212 and in the absence of a magnetic field, the output is off. The polarity independence and minimal power requirements allow these devices to easily replace reed switches for superior reliability and ease of manufacturing, while eliminating the requirement for signal conditioning. Improved stability is made possible through chopper stabilization, which reduces the residual offset voltage normally caused by device over-moulding, temperature dependencies and thermal stress. This device includes on a single silicon chip a hall-voltage generator, small-signal amplifier, chopper stabilization, a latch and a MOSFET output. Advanced CMOS processing is used to take advantage of low-voltage and low-power requirements, component matching, very low input-offset errors.
  • Chopper stabilized
  • Superior temperature stability
  • Extremely low switch-point drift
  • Insensitive to physical stress
  • High ESD protection
  • Solid-state reliability
