The ACS758 consists of a precision, low-offset linear Hall sensor circuit with a copper current path close to the product. The current applied through the copper current path is capable of generating a magnetic field that can be induced by the integrated Hall IC and converted to a proportional voltage. Device accuracy is optimized by placing the magnetic signal close to the Hall sensor. The accurate, high-precision output voltage is provided by a stable chopper-type, low-bias BICMOS IC that has been programmed for accuracy. The internal resistance of the read conduction path is typically 100 Q with low power loss. The thickness of the copper wire runs under high overcurrent conditions. The terminals of the conduction path and the sensor pins (pins 1 to 3) are electrically blasted. In this way, the ACS758 sensor 1C series can be used in applications that require electrical insulation but use -insulators or complex insulation techniques. The ACS758 device is fully calibrated prior to shipment from the factory. The ACS758 series is a lead-free product. All pins are plated with 100% fog and no lead is present in the package. working voltage: 3V-5V (MAN SV) static output voltage: VCCi2 Working current: 135m2A (MAX) storage temperature range: -65- 165 the maximum output current (VIOUT-GND): 3mA internal bandwidth: 120 KHz size:55 x 21 x 15mm Material:ABS colour:purple Package Contents: 1 x ACS758 Current Module Only the above package content, other products are not included.
