  • Product introduction

Allegro®The ACS715 provides an affordable, precision solution for DC current sensing in automotive systems. The device is packaged for easy customer implementation. Typical applications include motor control, load detection and management, switching power supplies, and overcurrent fault protection.

The device has a precise low biasLinear Hall sensorscircuit, and its copper current path is close to the surface of the wafer. The current applied through this copper current path generates a magnetic field that can be sensed by the integrated Hall IC and converted into a proportional voltage. Device accuracy is optimized by placing the magnetic signal close to the Hall sensor. The precise proportional voltage is provided by a chopper-stable, chopper-type low-bias BiCMOS Hall IC that is programmed for post-package accuracy.

The output of the device has a positive slope (>V) as the current rises through the primary copper current path (from pins 1 and 2, to 3 and 4) that are used as the current sensing pathIOUT(Q))。 The internal resistance of this conduction path is typically 1.2 mΩ, which has low power dissipation. The size of the copper wire allows the device to operate under overcurrent conditions of up to 5×. The terminals of the conduction path are electrically insulated from the sensor pins (pins 5 through 8). This allows the ACS715 current sensor IC to be used in applications that require electrical isolation without the use of opto-insulators or other expensive insulation technologies.

The ACS715 is available in a small surface mount SOIC8 package. The lead holders are 100% matte tin plated and are compatible with standard lead-free printed circuit board assembly processes. Internally, the device is lead-free except for the current RoHS-exempt high-temperature leaded solder balls used in the flip method. The device is fully calibrated before shipping from the factory.
