ACS71240
Automotive-Grade, Galvanically Isolated Current Sensor IC
with Common-Mode Field Rejection and Overcurrent Detection
in Small Footprint Low-Profile Packages
FEATURES AND BENEFITS DESCRIPTION • AEC-Q100 automotive qualified
• Differential Hall sensing rejects common-mode fields
• 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 techniques
• High bandwidth 120 kHz analog output for faster
response times in control applications
• Patented integrated digital temperature compensation
circuitry allows for near closed-loop accuracy over
temperature in an open loop sensor
• Single supply operation with nonratiometric output at
3.3 and 5 V options
• Overcurrent FAULT available between 50% and 200% IP
with 1.5 µs (typ) response time
• Non-ratiometric output provides immunity to noisy supplies
• Small footprint QFN-12 with wettable flank and SOIC-8 …
