Allegro ™ ACS725 current sensor IC industry, car industry, business and communication system of ac/dc sensor precision economic solutions. Small package is very suitable for the application of the space is narrow, due to reduced the area of the circuit board, also reduced the cost. Typical applications include motor control, load detection and management, switch power supply, and overcurrent fault protection.

This device has low precision, linear hall sensor circuit, migration and have copper pathway in near the surface of the wafer. Through the current application of the copper conduction path can be generated can be integrated hall IC and translated into is proportional to the voltage of the induced magnetic field. Current sensor in the form of difference, in order to suppress the common mode field, improving the measuring accuracy of in magnetic noise environment. Through the magnetic field with hall sensor near to optimize the inherent precision device. Low offset, chopping stability BiCMOS hall IC to provide accurate proportion voltage, the IC after encapsulation pass accuracy programming. Through a copper conductor path (from pins 1 and 2 to pin 3 and 4) the current increases, the device's output has a positive slope, the path is used for electrical measuring flu. The transmission path of conventional internal resistance is 1.2 m Ω, has lower power consumption.

Conduction path of terminals and sensor wire (pin 5-8) using electrical isolation. Which can be used in high level current sensing applications ACS725 current sensor, and the need for high level side differential amplifier or other expensive isolation technique.

ACS725 adopts flat on the surface of the small SOIC8 package installation. Fog pin frame with 100% of tin plating, with standard lead (Pb) printed circuit board assembly process compatible. The device's internal lead-free, except flip chip high temperature lead based solder ball, now this device belongs to RoHS exemption product. The device in the factory before shipment, after full calibration.

Differential hall sensing suppress common mode field

1.2 m Ω a conductor, low power loss, large capacity of impact resistance current.

Integrated block actually eliminate the conductor from current to the capacitive coupling of the chip, inhibit the high dv/dt output noise caused by transient

With the proprietary amplifier and filter design techniques, this device has the industry leading performance, noise and bandwidth also improved significantly

High bandwidth 120 KHz analog output to shorten the response time in control applications.

Allows users to filter pin with lower bandwidth filter output signal, in order to improve resolution

By using patent integrated digital temperature compensation circuit, you can obtain approximate closed loop in open loop sensor temperature measurement accuracy.

Small flat SOIC8 package suitable for space applications

Filter pin simplifies the bandwidth limitations, can get better resolution in low frequency.

3.3 V single-supply operation

The output voltage is proportional to the ac/dc current

Factory calibrated and static output voltage sensitivity to achieve higher accuracy

Stable chopper extremely stable static output voltage

Nearly zero hysteresis

The power supply voltage is proportional to the output
