MT3411A-EN

MT3411-EN Latch, Hall-Effect Magnetic Position Sensor 1 Product Description The MT3411-EN family is produced by BCD technology with both high performance and high reliability. The Hall IC internally includes an on-chip Hall voltage generator, a voltage regulator for operation with supply voltage of 2.8V to 24V, a smallsignal amplifier, Hall sensors with dynamic offset cancellation, a schmitt trigger and an open-drain output with over-current protection. It features temperature compensation technique to make the magnetic switching points stable over a wide temperature range. Other key features such as reverse supply voltage protection, output over-current protection and ESD level exceeding ±6KV (HBM) make the IC extremely robust and fault tolerant, which is important in demanding application environment such as automotive. Its extremely low operating supply voltage 2.8V also makes it possible to add external resistance in series with the supply pin for even greater protection against high voltage transients from the power supply. 4 Applications ￭ ￭ ￭ ￭ When the magnetic flux density (B) is greater than the operating point (BOP), the output turns on (Low). The output is held steady till the magnetic flux density (B) is less than the releasing point (BRP), at which point it turns off (High). 5.
