• Omnipolar or unipolar operation
• Integrated digital signal processing for

compensation
Compared with existing Hall effect sensors, the Si720x family offers industry-leading
sensitivity, which enables use with larger air gaps and smaller magnets. For battery-
powered applications, the Si720x family offers very low power consumption to improve
operating life.
• Low 400 nA Typical Current Consumption
at 5 samples per second
• Selectable Sensitivity, Hysteresis, Output
Polarity and Sample Rate
• Sensitivity Drift < ±3% over Temperature
The Si720x devices are offered in 3-pin SOT23, 5-pin SOT23, and TO-92 packages,
with power, ground, a single output pin that goes high or low as the magnetic field in-
creases, and with the 5-pin parts a disable(sleep) pin, and a tamper output pin. With the
three-pin package, tamper indication is by the pin going back to its zero field level at
high magnetic field.

2. Idle time can be factory programmed from 13.2 μsec to 206 msec ±10% or set to zero in which case conversions are done every
8.8 μsec. Normally idle time is only used at higher sample speeds.
3. For high voltage parts (VDD = 26.5 V maximum), the power on ramp should be faster than 10 V per second in the start-up region
from 2 to 3 V.

Si720x Switch/Latch Hall Effect Magnetic Position Sensor Data Sheet
Functional Description
2. Functional Description
The Si7201/2/3/4/5/6 family of Hall Effect magnetic sensors digitize the component of the magnetic field in the z axis of the device (pos-
itive field is defined as pointing into the device from the bottom). The digitized field is compared to a pre-programmed threshold and the
output pin goes high or low if the threshold is crossed. The parts are normally used to detect the presence or absence of a magnet in
security systems, as position sensors or for counting revolutions.

High voltage latches
The output pin (push pull or open collector) can go high or low when the magnetic field crosses a threshold. The output pin configura-
tion is determined by the type of part ordered.
The parts are preconfigured for the magnetic field measurement range, magnetic field operate and release points, sleep time, tempera-
ture compensation, tamper threshold and digital filtering and will wake into this mode when first powered. The specific configuration
output type (open collector or push pull) are determined by the part number. See Magnetic Sensors Selector Guide for details.

DISABLE Pin Timing
3. DISABLE Pin Timing
For a part that has a DISABLE pin, DISABLE high will put the part in complete sleep mode with IDD typical of 50 nA. When DISABLE
goes low, the part will wake and initiate a measurement. For a single measurement, this takes 11 μsec typically. Additional measure-
ments in a burst take 8.8 μsec. Once the measurement (burst) is complete, the output pin status is updated and the part enters idle
mode. The part will make a new measurement or measurement burst at the time-interval determined by the idle timer (typically 1 msec).
The idle timer is reset when DISABLE transitions from high to low, so the time from the first measurement until the next measurement
will always be the programmed idle time.
Disable low pulses can be as short as 1 μsec. For pulses shorter than a conversion burst, the part will make one burst and then go back
to sleep.
When disable returns high, a measurement in progress (if any) will complete and the part will enter sleep mode.
As the idle time is typically long (i.e. 1 msec) compared to the measurement time (i.e. 11 μsec), it is possible to keep the DISABLE pin
low duration short (i.e. 15 μsec) and have a long period in the sleep state. This is an effective way to control the sample rate and power.
For example, if the part is programmed to make a single measurement at a time and is programmed with an idle time of 1 msec and
DISABLE is pulsed low for 15 μsec every 50 msec, then the average IDD will be:
• 11 μsec to wake and make a measurement at IDD typical of 5.0 mA (3.3V)/(50.015 msec cycle time) = 1.0 μA
• 4 μsec in idle mode at typical current of 600 μA/(50.015 msec cycle time) = 0.05 μA
• 50 msec in sleep mode at 50 nA/(50.015 msec cycle time) = 0.05uA
• Or 1.1 μA total
As the programmed idle time is shorter than the DISABLE low time in the example, the value of the programmed idle time does not
make a difference.

For information on the below specifications of each OPN please refer to the Magnetic Sensors Selector Guide:
• Current Consumption
• Amount of digital filtering applied to the samples
• Time between measurements
• Temperature compensation
A temperature compensation can be applied to the field data to adjust for the variation in field with temperature for common magnet
types.
Note: North pole of a magnet at the bottom of a SOT23 package, top of a DFN 8 package(coming soon) or front of a TO92 package is
defined as positive field.
