ACS732 and ACS733
1 MHz Bandwidth, Galvanically Isolated Current Sensor IC in SOIC-16 Package
FEATURES AND BENEFITS
AEC-Q100 automotive qualified High bandwidth, 1 MHz analog output Differential Hall sensing rejects common-mode fields High-isolation SOIC16 wide body package provides
galvanic isolation for high-voltage applications Integrated shield virtually eliminates capacitive coupling
from current conductor to die, greatly suppressing output noise due to high dv/dt transients Industry-leading noise performance with greatly improved bandwidth through proprietary amplifier and filter design UL60950-1 (ed. 2) certified □ Dielectric Strength Voltage = 3.6 kVRMS □ Basic Isolation Working Voltage = 616 VRMS Fast and externally configurable overcurrent fault detection 1 mΩ primary conductor resistance for low power loss and high inrush current withstand capability Options for 3.3 V and 5 V single supply operation Output voltage proportional to AC and DC current Factory-trimmed sensitivity and quiescent output voltage for improved accuracy Nearly zero magnetic hysteresis Ratiometric output from supply voltage
PACKAGE: 16-Pin SOICW (suffix LA)
Not to scale
CB Certificate Number: US-23711-A2-UL
