20A ACS712 Current Sensor<\/span><\/h2>\n

The 20A ACS712 Range Current Module ACS712 consists of a precise, low-offset, linear\u00a0Hall circuit\u00a0with a copper conduction path located near the surface of the die. Applied current flowing through this copper conduction path generates a magnetic field in which the\u00a0Hall IC\u00a0converts into a proportional voltage.<\/span><\/p>\n

Sensing and controlling current flow is a fundamental requirement in a wide variety of applications including, over-current protection circuits, battery chargers, switching mode power supplies, digital watt meters, programmable current sources, etc.<\/span><\/p>\n
