Magn Tek MT3602A

The MT3602 is a Hall- effect based gear tooth sensor IC for automotive camshaft sensing application. MT3602 is used with a bias magnet with south- pole facing the back side (unbranded side) of the IC. The chip incorporates a Hall- effect plate, an A/D converter with self- calibration technique to adjust the internal gain for air- gap variation, a digital sample- and- hold circuit, a Schmitt trigger and an open- drain output with short- circuit protection.

As the gear tooth rotates, the chip senses the increase and decrease of the flux density. When the flux density increase exceeds a pre- defined hysteresis level (BHYS), the output turns on (BOP) When the flux density decrease exceeds the hysteresis level (BHYS), the output turns off (BRP)

The MT3602 is ideal for use to detect speed, position and direction in gear- tooth based applications. It is particularly suitable for applications that require accurate duty cycle and accurate edge detection, such as automotive camshaft sensing.
