Package
The ACS722LLCTR-20AB-T has a package type of SOICN-8.
Pinout
The ACS722LLCTR-20AB-T is an open-loop current sensor with a SOICN-8 package. It has eight pins, their functions are as follows:
VCC (Power Supply) - Pin 1: Connects to the positive power supply (3.3V or compatible).
GND (Ground) - Pin 6: Connects to the ground of the system.
OUT (Current Output) - Pin 4: Outputs a voltage proportional to the current flowing through the sensor.
SCL (Serial Clock) - Pin 7: Not used for this specific model, as it's an open-loop current sensor without serial communication.
SDI (Serial Data Input) - Pin 8: Not used for this specific model, as mentioned earlier.
In summary, the ACS722LLCTR-20AB-Т has eight pins with VCC (Pin 1), GND (Pin 6), OUT (Pin 4) and non-functional SCL (Pin 7), SDI (Pin 8)).
