Cross chip · Current Sensors · SOP-8

CC6937S8-5FB020 from Cross chip, 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 Primary current input pin, paired with pin 2 on the IP+ side; current flowing from IP+ to IP- is positive, and the internal primary conductor resistance is typically 0.5 mΩ.
2 IP+ passive Primary current input pin, paired with pin 1 on the IP+ side; current flowing from IP+ to IP- is positive, and the sensor should be connected in series with the measured circuit without shunt resistors across IP+ and IP-.
3 IP- passive Primary current return pin, paired with pin 4 on the IP- side; current flowing into IP- from IP+ is treated as the positive direction, and reverse current is negative.
4 IP- passive Primary current return pin, paired with pin 3 on the IP- side; the primary side is isolated from the secondary pins 5-8 with 3750 VRMS withstand voltage.
5 GND power_in Ground reference for the sensor's secondary circuit and the VOUT and VREF outputs.
6 VREF power_in Reference voltage pin that works as an output (2.500 V nominal in the 5 V series, recommended load about 2 mA) or as an input accepting 0 to 4 V, and it sets the VOUT quiescent level.
7 VOUT output Analog output whose quiescent level is VREF (2.5 V at 5 V supply) and which moves by IP × 100 mV/A for the CC6937S8-5FB020, with a 1.5 kΩ minimum load and 1 to 2.2 nF filter capacitor recommended.
8 VCC power_in Supply voltage pin; the 5 V series runs from 4.5 to 5.5 V and the absolute maximum rating is 6.5 V.
