AH1887-ZG-7 from Diodes Incorporated, in a SOT-553-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	Out2	output	Active-low CMOS output driven by the north-pole Hall channel. Asserts low when magnetic flux density B < Bop(n) (typ -35 G) and releases high when B > Brp(n) (typ -20 G). VOL <= 0.2 V at 0.5 mA; VOH >= Vdd-0.2 V at -0.5 mA.
2	GND	power_in	Device ground reference for supply and output stages.
3	NC	unconnected	No internal connection. Leave floating or tie to ground.
4	Vdd	power_in	Supply voltage input, 1.65 V to 3.3 V recommended operating range (5 V absolute max). Average supply current ~7 µA typ, 12 µA max at 1.8 V.
5	Out1	output	Active-low CMOS output driven by the south-pole Hall channel. Asserts low when magnetic flux density B > Bop(s) (typ 35 G) and releases high when B < Brp(s) (typ 20 G). VOL <= 0.2 V at 0.5 mA; VOH >= Vdd-0.2 V at -0.5 mA.
