Si720x Switch/Latch Hall Effect Magnetic Position Sensor Data Sheet The Si7201/2/3/4/5/6 family of Hall effect magnetic sensors switches and latches from Silicon Labs combines a chopper-stabilized Hall element with a low-noise analog amplifier, 13-bit analogto-digital converter, and a flexible comparator circuit. Leveraging Silicon Labs' proven CMOS design techniques, the Si720x family incorporates digital signal processing to provide precise compensation for temperature and offset drift.

Sleep is lower power, but the fastest sampling rate is 8 kHz. Idle allows sampling rate to be configured to be as high as 113 kHz. See the ordering guide for details. Time from VDD > 1.71 V to first measurement - 1 msec Note: 1. TAMPERb and DIS pin specifications apply when the pin is present (Si7203/4). 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. silabs.com | Building a more connected world.

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 (positive 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. Table 2.1. Part Ordering Guide Part Number Description Si7201 Low voltage switches Si7202 Low voltage latches Si7203 Low voltage switch with tamper and/or disable pins Si7204 Low voltage latches with tamper and/or disable pins Si7205 High voltage switches Si7206 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 configuration 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, temperature 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.

Rev. 1.4 | 9 Si720x Switch/Latch Hall Effect Magnetic Position Sensor Data Sheet 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 measurements 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. silabs.com | Building a more connected world.
