The 2SS52M with Board Mount Hall Effect / Magnetic Sensors 20mA Omnipolar radial lead IC pkg by Honeywell is an integrated circuit designed to sense the presence of magnetic or metallic fields. The device integrates an amplifying linear Hall Effect transistor, Hall-voltage generator, Schmitt trigger, power regulator, open-collector output transistor, and quiescent current compensation circuitry in a single package. It features a wide operating voltage range of 4.5V to 24V, extremely low quiescent current, and a low-power shutdown mode. The IC is rated for a minimum ambient temperature of -40°C, and has an operating range up to 100°C. Its output can source or sink up to 20mA, and its interior components are protected against shock and vibration. The 2SS52M is an ideal choice for magnetically actuated toy switches, small sensing magnets, and consumer electronics.
