OPT3001: pull-up and interrupt

Part Number: OPT3001

Hi,

When using the interrupt mechanism of the OPT3001 in both hysteresis-style comparison mode and latched mode, the interrupt pin is still pulled high thanks the the pull-up resistor configured on the microcontroller.

The voltage drops from 2.8V to 2.3V when light is applied to the sensor.

Do you have an idea of the cause of this problem ?

Thanks,

Titouan
