CH70140AB5PR

COSEMITECH · Current Sensors · SOP-8

CH70140AB5PR from COSEMITECH, 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 Terminal for the current being sensed, fused internally; the primary conductor runs from pins 1 and 2 to pins 3 and 4.
2 IP+ passive Terminal for the current being sensed, fused internally; the primary conductor runs from pins 1 and 2 to pins 3 and 4.
3 IP- passive Terminal for the current being sensed, fused internally; the output has a positive slope when current flows from pins 1 and 2 to pins 3 and 4.
4 IP- passive Terminal for the current being sensed, fused internally; the output has a positive slope when current flows from pins 1 and 2 to pins 3 and 4.
5 GND power_in Signal ground terminal; the primary conductor terminals are electrically isolated from pins 5 through 8.
6 FILTER passive Terminal for an external capacitor that sets the bandwidth of the device.
7 VIOUT output Analog output signal, proportional to the sensed current and ratio-metric to the supply; limited to VCC + 0.5 V maximum per the absolute maximum ratings.
8 VCC power_in Device power supply terminal; absolute maximum supply voltage is 6 V, and this variant (CH70140AB5*) is specified for 5 V ±0.5 V.
