Si721x Field Output Hall Effect Magnetic
Position Sensors Data Sheet
The Si7211/2/3/4/5/6/7 family of Hall-effect sensors from Silicon Labs combines a chopper-stabilized Hall element with a low-noise analog amplifier, 13-bit analog to digital converter. After A/D conversion the magnetic field data is available in analog. PWM or
SENT format (depending on the part number). Leveraging Silicon Labs' proven CMOS
design techniques, the Si721x family incorporates digital signal processing to provide
precise compensation for temperature and offset drift.
FEATURES
• High-sensitivity Hall-Effect Sensor
• Low noise output corresponding to
magnetic field
• Integrated digital signal processing for
temperature and offset drift
compensation
Compared with existing Hall-effect sensors, the Si721x family offers industry-leading
sensitivity and low noise, which enables use with larger air gaps and smaller magnets.
In the simplest case, the Si721x devices are offered in a 3 pin SOT23 or TO92 packages with power, ground, and a single output pin that is signal corresponding to the
magnetic field in analog, PWM, or SENT format.
• Low 50 nA Typical Sleep Current
Consumption
The Si721x devices are also offered in a 5 pin SOT23 and an 8 pin DFN(coming soon)
packages where the additional pins can be used for sleep mode (DIS) or to activate an
on-chip coil for built in self-test (BISTb).
• Sensitivity Drift < ±3% Over Temperature
• Configurable Sensitivity, Output Polarity
and Sample Rate
• Wide power supply voltage
• 1.7 to 5.5 V
• 3.3 to 26.5 V
Applications
• Configurable output options
• Analog
• Mechanical position sensing in consum- • Fluid level sensing
• Control knobs and selector switches
er, industrial applications
• Camera image stabilization, zoom, and
autofocus
• PWM
• SENT
• Industry-Standard Packaging

Functional Description
2. Functional Description
The Si7211/2/3/4/5/7 family of Hall Effect magnetic sensors digitize the component of the magnetic field in the z axis of the device (positive field is defined as pointing into the device from the bottom). The digitized field is then converted to an output format of analog,
PWM or SENT and presented on the output pin.

Refer to the Magnetic Sensors Selector Guide for the two digit number after the die revision which gives more details about output,
sampling frequency and other details.
Data output is always unsigned. That is, half scale (VDD/2 for analog out parts, 50% duty cycle for PWM output parts and 2048 (0x800)
for SENT output parts) corresponds to zero field.
The parts are preconfigured for the magnetic field measurement range, idle time, temperature compensation 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.

3. Analog Output
For the Si7211, the analog output is VDD/2 at zero field and goes from nearly zero at large negative field to nearly VDD at large positive
field.

4- and 5-pin packages also have the option of a BISTb pin. When configured and detected low, the internal coil is turned on until the pin

For high voltage parts (Si7216), the output is ratiometric to an internally derived VDD of 5V (± 5%) so long as the input VDD is > 6 V.

PWM Output Description
4. PWM Output Description
The PWM output can be configured as open drain or push pull. High voltage parts can only be configured as open drain. The PWM duty
cycle is factory configured and is normally set to in the range of 10 Hz to 1 KHz and is ±5%. See ordering guide for specific part numbers..
As each measurement completes, the next PWM cycle will be updated to reflect the last measurement result. The duty cycle varies
from 0 to 100% where 50% duty cycle means zero field, 0 % duty cycle generally means maximum negative field (-20.47 mT or -204.7
mT) and 100% duty cycle generally means maximum positive field (+20.47 or +204.7 mT). The high portion of the PWM is output first
so that

SENT Output
5. SENT Output
The Si7213 and Si7215 output data in SENT (Single Edge Nibble transmission) format conforming to J2716 January 2010. All SENT
output parts are configured as open collector.
SENT protocol messages consist of:
• A calibration/synchronization period consisting of 56 clock ticks
• A status and serial communication 4-bit nibble
• A sequence of up to six data nibbles
• A one nibble checksum
• Each nibble is 12 to 27 clock ticks
• An optional delay pause pulse
Figure 5.1. SENT Timing Diagram
As can be seen, each part of the sequence is determined by the timing between falling edges of the open drain sent output. First, a time
of 56 clock ticks is produced so that the receiver can calibrate itself to the Si7213/5 speed. Then a total of 8 nibbles (4 bits per nibble) is
produced. The edge to edge time of each nibble is 12 clock ticks for a data nibble of 0000b 13 ticks for a data value of 0001b and so on
up to 27 ticks for a data value of 1111b.
The nominal tick time has been standardized at 5 μsec (±5%) however this is configurable.
5.1 tSENT Status Nibble
In the Si721x the four bit status nibble is defined as follows:
• Bit 3 and Bit 2 always transmitted as zeroes (No serial message support)
• Bit 1 and Bit 0
• 00 Normal; No error condition
• 01 Error condition
• 10 Positive field BIST active
• 11 Negative field BIST active

5.2 SENT Data Nibbles
The Si7213 and Si7215 are configurable to support a variety of options. The standard option follows J2716 A.3 where:

3
An inverted copy of signal 1 data 1
For magnetic field, 3 nibbles are put together for a total 12 bit data word with values that can range from 0 to 4095. For magnetic field
data, 2048 corresponds to zero field. The Si7213 can be configured for ± 20.47 mT full scale or ± 204.7 mT full scale. On the 20.47 mT
full scale 1 LSB is 0.01 mT and on the 204.7 mT full scale 1 LSB is 0.1 mT.
5.3 CRC Calculation
The CRC is calculated based on the 6 data nibble according to x4 +x3 + x2 + 1 with a seed value of 0101 as per the recommendations
in J7216 section 5.4.2.2. The legacy CRC calculation is not supported.
5.4 SENT Pause Pulse
The Si7213 and Si7215 are configurable for a pause pulse that is 12 ticks low, 256 ticks wide. However, the standard offering is no
pause pulse.
5.5 SENT Frame Rate
For the standard offering with no pause pulse, each message will be 154 to 270 ticks in length. At a tick time of 5 μsec this is 770 to
1350 μsec. This gives an average frame rate of approximately 1 msec for the standard tick time of 5 μsec. Conversion start is
synchronized to the start of the synch pulse and is normally completed before the synch pulse completes so the data that is reported is
the data obtained during the synch pulse time.
5.6 BIST Activation During SENT Operation
For 3-pin packages BIST can be activated by holding the output pin low for the entire message.
Once BIST is activated SENT messages resume 12 ticks after the SENT IO pin is detected high. Eight positive field BIST messages
are followed by eight negative field BIST messages followed by a return to normal messages.
The nominal magnetic field output of the on-chip generator varies with coil current. The coil current varies with the coil resistance and
power supply voltage, so the nominal magnetic field output varies according to:
Bout = BperVnom x VDD
BperVnom is 1.6 mT/V
This can be used to calculate the expected magnetic field from the test coil for a given VDD. This is somewhat temperature dependent,
so the actual measured field will vary according to the accuracy of the part as well as temperature. Generally, as the coil is turned on
and off the measured variation in field should be within ±25% of expectation based on the calculated field generation.
The host processor should look for a variation in the magnetic field output to determine the entire system is working properly.
The 4- and 5-pin packages also have the option of a BISTb pin. When configured and detected low, the internal coil is turned on until
the pin is detected high again. Each subsequent BISTb activation flips the polarity of the coil during BIST.

Additional Information
For information on the below specifications of each OPN refer to the Magnetic Sensors Selector Guide:
• Current consumption
• Built in self test if applicable
All Si721x parts periodically measure the field and output the data in PWM, SENT, or analog format.
The Si721x parts are factory configurable for:
• The type of output analog, SENT, or PWM
• The amount of digital filtering applied to the samples
• The time between measurements
• The output pin can be open drain or push pull (SENT and PWM parts)
• Full scale can be programmed as 20mT or 200mT
• 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(coming soon) is defined as positive field.
