ACS759xCB  
Thermally Enhanced, Fully Integrated, Hall Effect-Based Linear Current Sensor IC  
With 100 μΩ Current Conductor and Optimized Performance at 3.3 V  
Features and Benefits  
Description  
Industry-leading noise performance through proprietary  
amplifier and filter design techniques  
The Allegro® ACS759 family of current sensor ICs provides  
economicalandprecisesolutionsforACorDCcurrentsensing.  
Typical applications include motor control, load detection and  
management, power supply and DC-to-DC converter control,  
inverter control, and overcurrent fault detection.  
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  
Total output error improvement through gain and offset  
trim over temperature  
Small package size, with easy mounting capability  
Monolithic Hall IC for high reliability  
Ultra-low power loss:100 μΩ internal conductor resistance  
Galvanic isolation allows use in economical, high-side  
current sensing in high voltage systems  
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.  
3.0 to 3.6 V, single supply operation

Application 1. The ACS759 outputs an analog signal, VOUT, that  
varies linearly with the bidirectional AC or DC primary current, IP,  
within the range specified. CF is for optimal noise management,  
with values that depend on the application.
