After The ES1220 exhibits latch magnetic switching characteristics. Therefore, it requires both south and north poles to operate properly. The OUT pin of these devices switches low (turns 4KV turn-on, the output voltage is VDSon. Note that the device www.innosensor.com 1 V1.2.2021 latches, that is, a south pole of sufficient strength towards the branded surface of the device turns the device on. The device remains on if the south pole is removed (B→0). This latching property defines the device as a magnetic memory. Based on BCD technology, InnoSen ES1220 is a Hall-effect device with high magnetic sensitivity. This multi-purpose latch suits most of the application requirements. The chopper-stabilized amplifier uses switched capacitor technique to suppress the offset generally observed with Hall sensors and amplifiers. The CMOS technology makes this advanced technique possible and contributes to smaller chip size and lower current consumption than bipolar technology. The small chip size is also an important factor to minimize the effect of physical stress. This combination results in more stable When the magnetic field is reduced below the release point, BRP, the OUT pin turns off (goes high). magnetic characteristics and enables faster and more precise design. The difference in the magnetic operate and release points is the hysteresis, BHYS, of the device. This built-in hysteresis prevents output oscillation near the switching point, and allows clean switching of the output even in the presence of external mechanical vibration and electrical noise. The operating voltage from 2.8V to 24V, low current consumption and large choice of operating temperature range according to “L”, and “E” specification make this device suitable for automotive, industrial and consumer applications. The device behaves as a latch with symmetric operating and release switching points (BOP=|BRP|).

Powering-on the device in the hysteresis region Operating Temperature Range (less than BOP and higher than BRP) allows an indeterminate output state. The correct state is attained after the first excursion beyond BOP or BRP. The SOT-23 device is reversed from the UA and DFN package. The SOT-23 output transistor will be latched on in the presence of a sufficiently strong North pole magnetic field applied to the marked face. www.innosensor.com Note: Exceeding the absolute maximum ratings may cause permanent damage.
