Description

The 5A 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.

• Low-noise analog signal path.
• Device bandwidth is set via the new FILTER pin.
• 5 µs output rise time in response to step input current.
• Small footprint, low-profile SOIC8 package.
• 2.1 kV RMS minimum isolation voltage from pins 1-4 to pins 5-8.
• 5.0 V, single-supply operation.
• 66 to 185 mV/A output sensitivity.
• Output voltage proportional to AC or DC currents.
• Factory-trimmed for accuracy.
• Extremely stable output offset voltage.
