Low Voltage Photosensor
In this thread is explained that a photodiode doesn't need a voltage across it to generate a photocurrent: 



Do you need all the functions integrated into one IC? You have plenty of options if you would pick a common photodiode plus a comparator. Comparators exist for DLV (Damn Low Voltages™) these days; Digikey lists more than a thousand which will happily run at 3.3 V or less. The MCP6546 is the cheapest I found:  


1.6 V to 5.5 V power supply  
open-drain output  
internal hysteresis


If the 30 mA current sink is not sufficient you can use the MCP6541, which has a push-pull output, from which you can drive an external transistor. This would also allow you to switch much higher voltages, as well as set your own hysteresis levels. In this answer I explain how to calculate the required resistances.
