ACS732 and ACS733  
1 MHz Bandwidth, Galvanically Isolated  
Current Sensor IC in SOIC-16 Package  
FEATURES AND BENEFITS  
DESCRIPTION  
• AEC-Q100 automotive qualified  
• High bandwidth, 1 MHz analog output  
• Differential Hall sensing rejects common-mode fields  
• High-isolation SOIC16 wide body package provides  
galvanic isolation for high-voltage applications  
• Industry-leading noise performance with greatly  
improved bandwidth through proprietary amplifier and  
filter design  
• UL60950-1 (ed. 2) certified  
□ Dielectric Strength Voltage = 3.6 kVRMS  
□ Basic Isolation Working Voltage = 616 VRMS  
• Fast and externally configurable overcurrent fault  
detection  
• 1 mΩ primary conductor resistance for low power loss  
and high inrush current withstand capability  
• Options for 3.3 V and 5 V single supply operation  
• Output voltage proportional to AC and DC current  
• Factory-trimmed sensitivity and quiescent output voltage  
for improved accuracy  
The ACS732 and ACS733 are a new generation of high  
bandwidth current sensor ICs from Allegro™. These devices  
provide a compact, fast, and accurate solution for measuring  
high-frequency currents in DC/DC converters and other  
switching power applications. The ACS732 and ACS733  
offer high isolation, high bandwidth Hall-effect-based current  
sensing with user-configurable overcurrent fault detection.  
These features make them ideally suited for high-frequency  
transformerandcurrenttransformerreplacementinapplications  
running at high voltages.  
TheACS732andACS733aresuitableforallmarkets,including  
automotive, industrial, commercial, and communications  
systems. They may be used in motor control, load detection  
andmanagement,switch-modepowersupplies,andovercurrent  
fault protection applications.  
The wide body SOIC-16 package allows for easy  
implementation. Applied current flowing through the copper  
conductionpathgeneratesamagneticfieldthatissensedbythe  
IC and converted to a proportional voltage. Current is sensed  
differentially in order to reject external common-mode fields.  
Deviceaccuracyisoptimizedthroughthecloseproximityofthe  
magnetic field to the Hall transducers. A precise, proportional  
voltageisprovidedbytheHallIC,whichisfactory-programmed  
afterpackagingforhighaccuracy.Thefullyintegratedpackage  
hasaninternalcopperconductivepathwithatypicalresistance  
of 1 mΩ, providing low power loss.  
• Nearly zero magnetic hysteresis  
• Ratiometric output from supply voltage  
PACKAGE: 16-Pin SOICW (suffix LA)  
The current-carrying pins (pins 1 through 8) are electrically  
isolated from the sensor leads (pins 9 through 16). This allows  
the devices to be used in high-side current sensing applications  
without the use of high-side differential amplifiers or other  
costly isolation techniques.
