BPH921

BPH921 High Sensitivity CMOS Hall-Effect Switch General Description The BPH921 is a Hall-effect latch designed in mixed signal CMOS technology. It is quite suitable for use in automotive, industrial and consumer applications. Superior high-temperature performance is made possible through dynamic offset cancellation, which reduces the residual offset voltage normally caused by device overmolding, temperature dependencies, and thermal stress. The device integrates a voltage regulator, Hall-voltage generator, small-signal amplifier, chopper stabilization, Schmitt trigger, and is directly drivable by the output. An integrated voltage regulator permits operation with supply voltage from 3.5V to 24V. Features  Wide Operating Voltage Range from 3.5 to 24V  Symmetrical Switch Points  Superior Temperature Stability  Chopper-stabilized Amplifier Stage  Compact Size  Built-in Pull-up Resistor  ESD Rating: 3500V (Human Body Model) Application  Brush...
