HACS712ELCTR-20A-T from HXY MOSFET, 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 | Positive measured-current input terminal; pins 1 and 2 are shorted together in the typical application, and the terminal withstands a transient surge current of 100 A for a 100 ms pulse. |
| 2 | IP+ | passive | Positive measured-current input terminal, shorted to pin 1 in the typical application, with the same 100 A / 100 ms transient surge rating on the current sampling terminal. |
| 3 | IP- | passive | Negative measured-current input terminal; pins 3 and 4 are shorted together in the typical application, and the current sampling terminal is rated for a 100 A transient surge over 100 ms. |
| 4 | IP- | passive | Negative measured-current input terminal, shorted to pin 3 in the typical application, with the same 100 A / 100 ms transient surge rating on the current sampling terminal. |
| 5 | GND | power_in | Ground reference pin for the sensor, also listed by the datasheet as a ground/programming pin; a filter capacitor CVcc is connected between VCC and this ground in the typical application. |
| 6 | TEST | unconnected | Factory testing pin that the datasheet describes as floating; it has no stated functional limits for application use. |
| 7 | OUT | output | Analog proportional output, with saturation of about 0.5 V low and VCC-0.3 V high at RL ≥ 4.7 kΩ, a load capacitance of 0.5 to 1 nF to GND, a source limit of 80 mA and a sink limit of 40 mA; also a signal output/programming pin. |
| 8 | VCC | power_in | Power supply input with operating range 4.5 V to 5.5 V (5 V typical) and a 6 V absolute maximum rating; also a power supply/programming pin, with a filter capacitor CVcc to GND recommended. |
