Si720x Switch/Latch Hall Effect Magnetic

Position Sensor Data Sheet

The Si7201/2/3/4/5/6 family of Hall effect magnetic sensors and latches from Silicon

Labs combines a chopper-stabilized Hall element with a low-noise analog amplifier, 13-

FEATURES

bit analog-to-digital converter, and a flexible comparator circuit. Leveraging Silicon Labs'

proven CMOS design techniques, the Si720x family incorporates digital signal process-

ing to provide precise compensation for temperature and offset drift.

• High-Sensitivity Hall Effect Sensor

• Maximum B operating point/minimum

field strength of <1.1 mT

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. For automotive applications, the Si720x family in SOT23 packages is

AEC-Q100 qualified.

• Omnipolar or unipolar operation

• Integrated digital signal processing for

temperature and offset drift

compensation

• Low 400 nA Typical Current Consumption

at 5 samples per second

The Si720x devices are offered in 3-pin SOT23 and TO-92 packages, with power,

ground, and a single output pin that goes high or low as the magnetic field increases.

With the three-pin package, tamper indication is by the pin going back to its zero field

level at high magnetic field.

• Selectable / Programmable Sensitivity,

Hysteresis, Output Polarity and Sample

Rate

• Sensitivity Drift < ±3% over Temperature

In the 5-pin SOT23 and 8-pin DFN(coming soon) packages, pins are available for both

sleep mode activation and separate tamper indication.

• Wide Power Supply Voltage

• 1.71 to 5.5 V

• 3.3 to 26.5 V

Applications:

• AEC-Q100 Qualified for Automotive

Applications

• Camera image stabilization, zoom,

• Replacement of reed switches in con-

sumer, automotive, and security applica-

and autofocus

• Selectable Output Options

• Open-drain output

• Fluid level sensing

tions

• Control knobs and selector switches

• Automotive position sensing of HVAC

valve, head rest, seat track, side mir-

rors, sunroof, door locks, and other me-

chanical devices

• Digital high/low output

• General-purpose mechanical position

sensing

• Industry-Standard Packaging

• Surface mount SOT-23 (3 or 5 pin)

• Through hole TO-92 (3-pin)

• BLDC motor control

• 1.4 x 1.6 mm 8-pin DFN package
