ACS712 20A Current Sensor Module

ACS712 20A Current Sensor Module 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 which the Hall IC converts into a proportional voltage. It provides economical and precise solutions for AC or DC current sensing in industrial, commercial, and communications systems.It is provided in a small surface-mount SOIC8 package. The lead frame is plated with 100 percent matte tin, which is compatible with standard lead (Pb) free printed circuit board assembly processes.

Features

• It has a low-noise Analog signal path
• The device bandwidth is set via the new FILTER pin
• The 5 s output rise time in response to step input current
• The small footprint, low-profile SOIC8 package
• It has a 5.0 V single-supply operation
• Output voltage proportional to AC or DC currents
• The factory-trimmed for accuracy
• It has extremely stable output offset voltage
• It has nearly zero magnetic hysteresis
• The radiometric output from the supply voltage
• Device bandwidth is set via the new FILTER pin

Applications

• Motor control
• Load detection and management
• Switched-mode power supplies
• Overcurrent fault protection.
