Current sensor pins.
Current sensor pins
- IP+ (current input positive) : a pin intended to be connected to the positive side of a circuit through which current flows in order to monitor it.
- IP- (negative current input) : a pin intended to be connected to the negative side of a circuit through which current flows for the purpose of monitoring it.
- VCC (logic power supply) : used to connect the supply voltage for the current sensor measurement system. The supply voltage should be between 4.5 V and 5.5 V.
- OUT : output of the system from which an analog voltage proportional to the measured current is read. This signal can be further processed or used for direct current monitoring.
- GND : system ground.
