[EE] Picking omnipolar Hall effect sensors

[Alan]

Late but...
I just spotted an omnipolar Hall effect ic from Rohm. Has two outputs that could probably be diode anded. One for each magnet polarity.
BU52075GWZ-E2
https://www.mouser.com/search/refine.aspx?Ntk=P_MarCom&Ntt=145692848
Draws 5uA
$.48 for one $.20ea for 100
Looking forward,

Like the ones that I mentioned, these obtain their low Iq by sampling the
inputs.
Nominal sampling interval is 50 mS but can be 100 mS worst case.

Outputs are true bipolar so as Allan says, ORing is needed.
Diodes 'should work' OK.

Package is either tiny or very tiny.
HVS0F5 1.6mm x 1.2mm is leaded.
VCSC50L1 is 1.1mm x 1.1mm mit bumps.
