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 over-
molding, 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

Note 1: Stress beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. Under “recommended operating
conditions” the device operation is assured, but some particular parameter may not be achieved. The electrical characteristics table defines the operation
range of the device, the electrical characteristics is assured on DC and AC voltage by the test program. For the parameters without minimum and maximum
value in the EC table, the typical value defines the operation range, the accuracy is not guaranteed by spec.
