8.5 Z-axis Range Indication (“Red/Yellow/Green” Indicator)
The NSE-5310 provides several options of detecting the magnet distance by indicating the strength of the magnetic field. Signal indicators
MagINCn and MagDECn are available both as hardware pins (pins 2 and 3) and as status bits in the serial data stream (see Figure 9) .
Additionally the LIN status bit indicates the non-recommended “red” range.
The digital status bits MagINC, MagDec, LIN and the hardware pins MagINCn, MagDECn have the following function:

YELLOW range: magnetic field is ~3.4-4.5mT.
The device may still be operated in this range, but with slightly reduced
accuracy.
RED range: magnetic field is <3.4mT (MAG <20) or >54.5mT
(MAG >5F). It is still possible to operate the device in the red range, but
not recommended.
8.6 Pulse Width Modulation (PWM) Output
The NSE-5310 also provides a pulse width modulated output (PWM), whose duty cycle is proportional to the relative linear position of the
magnet within one pole pair (2.0 mm). This cycle repeats after every subsequent pole pair:
t on ? 4098
( t on + t off )
Position = ------------------------ – 1
(EQ 1)
Where:
Digital position = 0 – 4094
Exception: A linear position of 1999.5μm = digital position 4095 will generate a pulse width of t ON = 4097μs and a pause t OFF = 1μs
The PWM frequency is internally trimmed to an accuracy of ±5% (±10% over full temperature range). This tolerance can be cancelled by
measuring the complete duty cycle as shown above.
Operating Conditions: T AMB = -40 to +125oC, VDD5V = 3.0~3.6V (3V operation) VDD5V = 4.5~5.5V (5V operation) unless otherwise noted.
