ACS717KMATR-10B-T データシート - Allegro MicroSystems

DESCRIPTION
The Allegro™ACS717 current sensor IC is an economical, high isolation solution for AC or DC current sensing in industrial, commercial, and communications systems. The small package is ideal for space constrained applications, though the widebody provides the creepage and clearance needed for high isolation. Typical applications include motor control, load detection and management, switched-mode power supplies, and overcurrent fault protection.

FEATURES AND BENEFITS
• IEC/UL 60950-1 Ed. 2 certified to:
    □ Dielectric Strength = 4800 Vrms (tested for 60 seconds)
    □ Basic Isolation = 1550 Vpeak
    □ Reinforced Isolation = 800 Vpeak
• Small footprint, low-profile SOIC16 wide-body package suitable for space constrained applications that require high galvanic isolation
• 0.85 mΩ primary conductor for low power loss and high inrush current withstand capability
• Low, 400 μARMS√Hz noise density results in typical input referred noise of 70 mA(rms) at max bandwidth (40 kHz)
• 3.3 V, single supply operation
• Output voltage proportional to AC or DC current
• Factory-trimmed sensitivity and quiescent output voltage for improved accuracy
• Chopper stabilization results in extremely stable quiescent output voltage
• Ratiometric output from supply voltage
