7.3.5.2 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 4 us after being exposed to a 80 uA current on the ADJ pin.

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

Figure 7-6 shows the relationship between BOP and VADJ.
