Theory of Operation

The LDC0851 is an inductance based switch for contactless and robust applications such as presencedetection, event counting, and coarse position detection. The device is connected to a reference coil(LREF) and a sensing coil (LSENSE). The output of the LDC0851 switches when the inductance ofLSENSE drops below LREF which is caused by an approaching metal target. The LDC0851 EVMemploys a stacked coil arrangement, in which the LSENSE sensor coil is closer to the metal target thanthe LREF reference coil when approached from the top side (LSENSE side). The user can take advantageof the Offset Adjust feature to change the switching distance (dswitch). The offset is added to LREF sothat increasing the ADJ code causes the LDC0851 to switch at a closer distance. The ADJ code isdetermined by the voltage level on the ADJ pin at device power on and by toggling the Enable pin lowthen high.

Figure 3-2. Switch Distance with Offset

A potentiometer (R5) has been included to make adjusting the threshold easier for prototyping. Note thatrotating the potentiometer clockwise towards the MIN direction decreases the ADJ value and results in alonger switching threshold. Similarly, rotating R5 counter clockwise towards the MAX position increasesthe ADJ value and decreases the switching distance. The Enable pin should be toggled low then high toset a new switching threshold.

Figure 3-3. Adjust the Offset

The ADJ value can be achieved by setting the combination of R4 + R5 to the values in Table 3-1.

The switching distance for each ADJ code can be approximated with Equation 1.

where• dswitch is the approximated switching distance threshold for stacked coils• dcoil is the coil diameter• ADJCode is the desired value from Table 3-1 (1)

For example, consider a coil with a diameter of 20 mm. An ADJ code of 1 yields a switching distance of5.6 mm, and an ADJ code of 15 yields a switching distance of 0.375 mm. This method helps reduce theeffort needed to design the coil ratio precisely for a specific switching distance. It should be noted that themaximum sensing distance is determined almost entirely by the diameter of the coil for spiral coils or bythe minimum outer dimension for non-spiral coils. It is also recommended to use a target of equal or largersize to the coil diameter to get the longest sensing range.

4.2 Adjust the ThresholdThe EVM has a potentiometer (R5) which can be used to control the voltage level on the ADJ pin. Rotatethe pot clockwise towards “MIN” so that ADJ value is in the minimum offset position, which has the longestsensing range.

Figure 4-5. Adjust the Offset

To set a new threshold, toggle the EN RESET switch (S1) to re-sample the ADJ pin. This must be doneevery time a new threshold is set.

www.ti.com Detecting presence of Metal Targets

4.3 Detecting presence of Metal TargetsWith no target is present the OUTPUT LED (D3) should be off. If D3 is on or remains on, increase theoffset with R5 and toggle EN with S1 as shown in the previous step.

Figure 4-7. Observe Status of OUT LED

Bring a conductive target close to the LSENSE coil. The OUT LED (D3) should turn on when the target is1 to 8 mm above the EVM sensing coil depending on the ADJ value.

Figure 4-8. Bring Metal Target Close to LSENSE

To change the switching threshold simply adjust the value of R5, toggle EN with S1 and retest. Note thatduring active operation the ADJ pin draws ~10 µA of current will alter the resistance reading if using amulti meter to check the value. In order to properly set or check the ADJ resistance when using a multimeter, turn off the device, remove the battery, and set S2 to BAT. The resistance measured across R4 +R5 should be set according to Table 3-1 for a desired ADJ setting.

This process can be repeated and fine-tuned for a variety of applications including open/close proximityswitches, white goods, home security and tamper detection, e-meters, and printers.
