Magnetic field sensing I2C digital interface

This magnetic sensor IC has a 7-bit serial address and supports I2C protocols with standard

and fast modes (100 kHz and 400 kHz, respectively), but does not support high-speed

mode (Hs).

External pull-up resistors are required to support the standard and fast modes. Depending

on the application, the internal pull-ups may be used to support slower data speeds than

specified by I2C standards.

This device does not contain 50 ns spike suppression, as required by fast mode operation in

the I2C bus specification.

Activities required by the master (register read and write) have priority over internal

activities, such as measurement. The purpose of this priority is to prevent the master waiting

and the I2C bus being engaged for longer than necessary.
