COSEMITECH · Current Sensors · SOIC-8

CH70110AB5PR from COSEMITECH, in a SOIC-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 Primary current-sense terminal (positive side). Pins 1 and 2 are fused internally and form one end of the low-resistance (0.8 mΩ typ.) copper conduction path used for current sensing. Current flows from pins 1,2 to pins 3,4 for a positive output slope.
2 IP+ passive Primary current-sense terminal (positive side). Pins 1 and 2 are fused internally and form one end of the low-resistance (0.8 mΩ typ.) copper conduction path used for current sensing.
3 IP- passive Primary current-sense terminal (negative side). Pins 3 and 4 are fused internally and form the return end of the internal copper conduction path.
4 IP- passive Primary current-sense terminal (negative side). Pins 3 and 4 are fused internally and form the return end of the internal copper conduction path.
5 GND power_in Signal-side ground reference for the Hall sensor front-end, output amplifier, and control logic.
6 FILTER passive External bandwidth-setting pin. Connect a filter capacitor CF from this pin to GND; it forms an RC low-pass with the internal 1.7 kΩ filter resistance (RF(int)) to trade bandwidth against noise. Typical application uses 10 nF for the specified 120 kHz -3 dB bandwidth.
7 VIOUT output Analog output voltage proportional to sensed primary current. Bidirectional (B) variant is ratio-metric with VCC and centered at VCC/2 at IP = 0 A; sensitivity is 200 mV/A (5 V supply). Drive with RL ≥ 4.7 kΩ and CL ≤ 10 nF.
8 VCC power_in Device supply pin. 5 V ±0.5 V for the AB5 variant; ICC = 10 mA typ. Bypass with 0.1 µF to GND close to the pin.
