ACS758xCB  
Thermally Enhanced, Fully Integrated, Hall Effect-Based  
Linear Current Sensor IC with 100 μΩ Current Conductor  
Features and Benefits  
Description  
Industry-leading noise performance through proprietary  
amplifier and filter design techniques  
The Allegro® ACS758 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  
3.0 to 5.5 V, single supply operation  
120 kHz typical bandwidth  
3 μs output rise time in response to step input current  
Output voltage proportional to AC or DC currents  
Factory-trimmed for accuracy  
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.  
High level immunity to current conductor dV/dt and stray  
electric fields, offered byAllegro proprietary integrated shield  
technology,guaranteeslowoutputvoltagerippleandlowoffset  
drift in high-side, high voltage applications.  
Extremely stable output offset voltage  
Nearly zero magnetic hysteresis

Application 1. The ACS758 outputs an analog signal, VOUT, that  
varies linearly with the uni- or bi-directional AC or DC primary  
sampled current, IP, within the range specified. CF is for optimal  
noise management, with values that depend on the application.
