CH70150AB5PR from COSEMITECH, in a SOP-8. 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 IP+ passive Terminal for current being sensed (positive side of primary conductor). Internally fused/tied to pin 2 through the 0.8 mΩ primary copper path. Electrically isolated from pins 5-8 by 3000 VRMS reinforced isolation.
2 IP+ passive Terminal for current being sensed (positive side of primary conductor). Internally connected to pin 1 through the primary copper conduction path. Typically tied to pin 1 externally to carry the sensed current.
3 IP- passive Terminal for current being sensed (return side of primary conductor). Internally connected to pin 4 through the primary copper path. Current flowing pin 1/2 → pin 3/4 produces a positive-slope output.
4 IP- passive Terminal for current being sensed (return side of primary conductor). Internally tied to pin 3 through the primary copper path. Typically tied to pin 3 externally.
5 GND power_in Signal ground terminal for the sensor / low-voltage side of the isolation barrier. Return for VCC and reference for VIOUT.
6 FILTER passive Terminal for external filter capacitor (CF) that sets output bandwidth. Together with the internal 1.7 kΩ filter resistor (RF(int)), CF forms an RC low-pass on the output signal path. Default −3 dB bandwidth is 120 kHz with CF = 0.
7 VIOUT output Analog output signal. Ratiometric to VCC; for the AB5 variant (VIOUT proportional to VCC), zero-current output ≈ VCC/2 with a slope of 40 mV/A (typical) over the ±50 A range. Drives loads down to RL = 4.7 kΩ; VOH ≥ VCC − 0.2 V, VOL ≤ 0.2 V.
8 VCC power_in Device power supply terminal. Nominal 5 V ± 0.5 V for the AB5 variant (3.3 V options exist as AB3 variants). Typical supply current ICC = 10 mA (14 mA max). Bypass locally with 0.1 µF to GND.
