NSE-5310
Datasheet - Application Information
8.2 Automatic Gain Control (AGC)
As the magnetic input field varies non-linearly with the air gap between sensor and magnet, the gain is controlled to an optimum input signal for
the SD ADC. The magnitude output is compared to a target register value. The most significant eight bits are used. If the actual magnitude differs
from the target value, an UP/DOWN signal for the AGC counter signal is generated.
For air gap detection functionality, two magnitude-change outputs are derived from the AGC counter UP/DOWN signals while the loop is
controlling the amplitude back to the target amplitude. Magnitude Increasing (MagINCn) and Magnitude Decreasing (MagDECn) signals indicate
air gap (SIN/COS amplitude) changes. Both signals are high for saturation of the AGC counter (running into upper / lower limit) and produce a
Non-Valid-Range alarm. The output pins can be connected together in wired-OR configuration to produce a single NVRn bit. For faster power-up
and response time, a successive approximation algorithm is implemented.
8.3 Temperature Sensor
The Temperature Sensor provides the junction temperature information over the serial interface.
Table 10. Temperature Sensor Characteristics
8.4 I2C User Interface
The device is accessible via an I2C two-wire serial interface. The default address is A<6:0>1000000. A<5:1> can be defined by the OTP I2C
Address. A0 can be selected by pulling up pin 11 (default internal pull down). CSn (default internal pull up) must be low during I2C data
transmission.
