6.3.5.2 Adjustable Voltage

One other way to setup the BOP is to apply a voltage to the "ADJ" pin. This voltage is directly proportional to the BOP value. The relationship between BOP and voltage is defined as BOP(mT)= VADJ(mV) × 0.0125. To apply a voltage on the "ADJ" pin, the voltage source must be able to settle within 4µs after being exposed to a 80µA current on the ADJ pin.

The device BOP must be set to any value between 2mT and 15mT. This means VADJ must be set between 160mV and 1200mV. Operating above and beyond those limits is not recommended and can result in either getting the wrong threshold set or locking up the device into a specific state without the possibility of exiting.

Figure 6-6 shows the relationship between BOP and VADJ.
