Full integration of ACS712: with 2.1 kVRMS voltage insulation and low resistance current conductor, linear current sensor based on Holzer effect IC
Allegro & reg; the acs712 provides economical and precise solutions for industrial, commercial and communication system of AC or DC current sensing. The device package is convenient for customers to easily implement. Typical applications include motor control, load detection and management, switching mode power supply, and overcurrent fault protection. The device is not available for automotive applications.
The device has a precise low bias linear Holzer sensor circuit with a copper surface near the wafer current path. By applying the copper conduction path current can generate can be integrated Hall sensor IC and transformed into a proportional voltage magnetic field. Through the close proximity of the magnetic signal Holzer sensor device accuracy optimization. Precise proportional to the voltage provided by the chopper stabilized low bias BiCMOS Holzer IC IC, the factory has been programmed for accuracy.
When used for current sensing measuring pathway mainly copper conduction path (from pin 1 and 2, 3 and 4) the rising current, the output device has a positive slope (>VIOUT (q)). The internal resistance pathway is usually m, with low power loss. The thickness of copper wire allows the device to run on up to 5 * overcurrent conditions. Terminal and sensor pin pathway (pin 5 to 8) between the electrical insulation. This allows the ACS712 current sensor IC can be used in applications requiring electrical isolation without the use of photoelectric insulation device or other expensive insulation technology.
ACS712 uses a small surface mount SOIC8 package. The leadframe is plated with 100% matte tin, with standard lead-free (Pb) printed circuit board assembly processes compatible. Inside, the device for the lead-free flip chip products, currently exempt from high temperature lead-free solder balls except RoHS. The device is fully calibrated prior to shipment from the factory.
