The MT816X family is produced by BCD technology with both high performance and high reliability. ESD level exceeding ±5.5 KV (HBM) make the IC extremely robust and fault tolerant, which is important in demanding application environment such as automotive.
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).
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.
