ACS712-20A Range Current Sensor Module

Description

The ACS712-20A Range 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 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.

Features :

1. The low-noise analog signal path
2. Device bandwidth is set via the new FILTER pin
3. 5 µs output rise time in response to step input current
4. Small footprint, low-profile SOIC8 package
5. 2.1 kV RMS minimum isolation voltage from pins 1-4 to pins 5-8
6. 5.0 V, single-supply operation
7. 66 to 185 mV/A output sensitivity
8. Output voltage proportional to AC or DC currents
9. Factory-trimmed for accuracy
10. Extremely stable output offset voltage
11. Nearly zero magnetic hysteresis
12. The ratiometric output from the supply voltage.
