Allegro MicroSystems ACS71240
The ACS71240 includes an integrated fault comparator for simplified overcurrent detection. The ultrafast response time provides the system with ample time to detect and protect against short-circuit events. The ACS71240 is provided in small, low-profile surface-mount package options: QFN-12 with wettable flank and SOIC-8.| Part No. | ACS71240 |

FEATURES AND BENEFITS
● 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
● Nonratiometric output provides immunity to noisy supplies
● Small footprint QFN-12 with wettable flank and SOIC-8 suitable for space-constrained automotive applications
● 0.6 mΩ (QFN-12) or 1.2 mΩ (SOIC-8) primary...
