Allegro ™ ACS717 current sensor IC is industrial, commercial and communication system of ac/dc sensing high isolation voltage economic solutions. Although wide-body structure can provide high isolation voltage required creepage distance and clearance, but small package is the ideal choice for space application. 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. Through the magnetic field with hall sensor near to optimize precision device. Low offset, chopping provide proportional voltage stability BiCMOS hall IC, the IC after encapsulation pass accuracy programming. Through a copper conductor path (from 1-4 to pin pin 5-8) current is added, the device's output has a positive slope, the path is used for electrical measuring flu. The transmission path of conventional internal resistance is 0.85 m Ω, has lower power consumption.
Conduction path of terminals and sensor wire (pin 10-15) with electrical isolation. Which can be used in high level current sensing applications ACS717 current sensor, and the need for high level side differential amplifier or other expensive isolation technique.
ACS717 USES small package installed on the surface of the flat SOICW16 suffixes (MA). This device is used lead-free products, 100% fog tin plating. The device in the factory before shipment, after full calibration.
IEC/UL 60950-1, Ed. 2 certification:
Dielectric strength = 4800 Vrms (60 seconds)
Base isolation voltage = 1550 Vpeak
Enhance the isolation voltage = 800 Vpeak
Small area of the flat SOIC16 wide-body assembly is suitable for the narrow space applications require high current isolation
0.85 m Ω a conductor, low power loss, large capacity of impact resistance current.
400 Hz low noise density mu A RMS) achieve the maximum bandwidth (40 kHz) typical reference noise 70 mA (RMS)
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
The power supply voltage is proportional to the output
