ACS773  
High Accuracy, Hall-Effect-Based, 200 kHz Bandwidth,  
Galvanically Isolated Current Sensor IC with 100 µΩ Current Conductor  
DESCRIPTION  
FEATURES AND BENEFITS  
• AEC-Q100 Grade 1 qualified  
• Typical of 2.5 μs output response time  
• 3.3 V supply operation  
The Allegro™ ACS773 family of current sensor ICs provide  
economicalandprecisesolutionsforACorDCcurrentsensing,  
idealformotorcontrol,loaddetectionandmanagement,power  
supply and DC-to-DC converter control, and inverter control.  
The 2.5 µs response time enables overcurrent fault detection  
in safety-critical applications.  
• Ultra-low power loss: 100 μΩ internal conductor resistance  
• Reinforced galvanic isolation allows use in economical,  
high-side current sensing in high-voltage systems  
• 4800 Vrms dielectric strength certified under UL60950-1  
• Industry-leading noise performance with greatly  
improved bandwidth through proprietary amplifier and  
filter design techniques  
• Integrated shield greatly reduces capacitive coupling  
from current conductor to die due to high dV/dt signals,  
and prevents offset drift in high-side, high-voltage  
applications  
• Greatly improved total output error through digitally  
programmed and compensated gain and offset over the  
full operating temperature range  
• Small package size, with easy mounting capability  
• Monolithic Hall IC for high reliability  
The device consists of a precision, low-offset linear Hall  
circuit with a copper conduction path located near the die.  
Applied current flowing through this copper conduction path  
generates a magnetic field which the Hall IC converts into a  
proportionalvoltage.Deviceaccuracyisoptimizedthroughthe  
close proximity of the magnetic signal to the Hall transducer.  
A precise, proportional output voltage is provided by the  
low-offset, chopper-stabilized BiCMOS Hall IC, which is  
programmed for accuracy at the factory. Proprietary digital  
temperature compensation technology greatly improves the  
IC accuracy and temperature stability.  
High-level immunity to current conductor dV/dt and stray  
electricfieldsisofferedbyAllegroproprietaryintegratedshield  
technology for low output voltage ripple and low offset drift  
in high-side, high-voltage applications.  
• Output voltage proportional to AC or DC currents  
• Factory-trimmed for accuracy  
• Extremely stable output offset voltage

Application 1: the ACS773 outputs an analog  
signal, VOUT, that varies linearly with the  
bidirectional AC or DC primary sensed cur-  
rent, IP, within the range specified. RF and  
CF are for optimal noise management, with  
values that depend on the application.
