Operating range 3.8 V to 40 V (absolute max -60 V to +60 V). Typical supply current 6 mA (max 9 mA at VSUP = 5 V). Includes reverse-voltage protection. |+| 2 | GND | power_in | Ground / device return. |+| 3 | VOUT | output | Open-collector Hall-switch output; requires an external pull-up resistor (typ RL = 4.7 kΩ). Sinks up to 30 mA (abs max 40 mA), Vsat ≤ 0.4 V at Iout = 20 mA. Output leakage ≤ 10 µA.
