ACS712-30A Current Sensor

OVERVIEW:

The 30A range Current Sensor Module ACS712 consists of a precise, low-offset, linear Hall circuit with 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 Hall IC converts into a proportional voltage.

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.

• The output voltage at +2 amps would be (2.5V + (0.066 * 2)) = 2.632 V
• The output voltage at -5 amps would be (2.5V - (0.066 * 5)) = 2.170 V
