Functional Description and Application Information
4.10
To supply Hall Effect Sensors or similar external loads, the HSUP output is implemented. To reduce power dissipation inside the
device, the output is implemented as a switchable Voltage Regulator, internally connected to the VS1 supply input. For protection,
an Over-temperature Shutdown and a Current Limitation is implemented. A write to the Hall Supply Register (HSR), when the
over-temperature condition is gone, will re-enable the Hall Supply Output.
The HSUP output is active only during Normal mode. A capacitor C
