ZHHXDZ · Hall Switches · SOP-8

HX723-40B-S from ZHHXDZ, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IP+ passive Sampled-current positive terminal of the primary conductor; absolute maximum continuous input current is 40 A, with 100 A peak allowed for 3 s.
2 IP+ passive Second sampled-current positive terminal of the primary conductor (datasheet lists it as a separate pin with the same function), with the same 40 A continuous and 100 A peak (3 s) limits.
3 IP- passive Sampled-current negative terminal of the primary conductor; absolute maximum continuous input current is 40 A, with 100 A peak allowed for 3 s.
4 IP- passive Second sampled-current negative terminal of the primary conductor (datasheet lists it as a separate pin with the same function), with the same 40 A continuous and 100 A peak (3 s) limits.
5 GND power_in Ground reference for the sensor and its output signals.
6 VZCR output Zero-current reference output at 0.5·VCC (2.470-2.530 V at VCC = 5 V); source current up to 400 µA and sink current up to 3000 µA.
7 OUT output Analog signal output, 50%·VCC at zero current and linear with sensed current; absolute maximum source current 6 mA and sink current 30 mA.
8 VCC power_in Supply voltage, operating range 4.5 V to 5.5 V (absolute maximum 7 V).
