Hall Effect Switch
High Sensitivity /Low Power Hall Effect Switch --BLH301
BLH301 Hall-effect sensor is a temperature stable, stress-resistant, Low Tolerance of Sensitivity micro-power switch. Superior high-temperature performance is made possible through a dynamic offset cancellation that utilizeschopper-stabilization. This method reduces the offset voltage normally caused by device over molding, temperature dependencies, and thermal stress.
BLH301 is special made for low operation voltage, 1.5V, to active the chip which is includes the following on a single silicon chip: voltage regulator, Hall voltage generator, small-signal amplifier, chopper stabilization, Schmitt trigger, CMOS output driver.
