ASEK716KLA-12CB-T

• Product Introduction

The Allegro® ACS716 current sensor provides an affordable and accurate solution for current sensing applications in industrial, commercial, and communication systems. The device comes in a small wall-mounted package for ease of user use.

The ACS716 device has an accurate linear Hall sensor IC with a copper current path close to the surface of the wafer. The applied current flows through the copper current path, while the analog output voltage of the Hall sensor IC linearly tracks the magnetic field generated by the applied current. The accuracy of the ACS716 is maximized thanks to this patented packaging device, as the Hall components are positioned in close proximity to the current to be measured.

Allegro's exclusive integrated screen technology provides high immunity to current conductor dV/dt signals and stray electric fields, ensuring low output voltage ripple and low bias drift in high-end, high-voltage applications.

The overcurrent voltage input (VOC pin) allows the user to set an overcurrent fault standard for this device. When the current flowing through the copper current path (between IP+ and IP– pins) exceeds this standard, the disconnected drain overcurrent fault pin goes into a logically low state. The write-only program of the ACS716's internal linear Hall sensor IC enables exceptionally accurate both analog and digital output signals.

The typical copper in-path resistance for current sensing is 1 mΩ with very little power loss. Moreover, the current path is isolated from the input and output of the low-voltage sensor. This allows the ACS716 sensor family to be used in applications where electrical isolation is required without the use of photoisolators or other expensive insulation technologies.

The ACS716 is available in a small surface-mount SOIC16 package. The pin frame is 100% matte tin plated and is compatible with standard lead-free printed circuit board assembly processes. The device does not contain lead inside, except for the current RoHS-exempt high-temperature leaded solder balls used in the flip method. The device is fully calibrated prior to shipment.
