CT417  
XtremeSense™ TMR Current Sensor  
with Ultra-Low Noise and <3% Total Error  
FEATURES AND BENEFITS  
DESCRIPTION  
The CT417 is a high bandwidth and ultra-low noise integrated  
contact current sensor that usesAllegro patented XtremeSense™  
TMR technology to enable high accuracy current measurements  
for many industrial, consumer, and automotive applications.  
The device supports eight current ranges where the integrated  
current carrying conductor (CCC) will handle up to 65 A of  
current and generates a current measurement as a linear analog  
output voltage. The device achieves a total output error of less  
than ±1.0% full-scale (FS).  
• Integrated contact current sensing for low to medium  
current ranges:  
0 to 20 A  
±20 A  
0 to 50 A  
±50 A  
0 to 30 A  
±30 A  
0 to 65 A  
±65 A  
±40 A  
• Integrated current carrying conductor (CCC)  
• Linear analog output voltage  
The device has a 300 ns output response time while the current  
consumption is ~6.0 mA and is immune to common mode  
fields. The CT417 has an integrated overcurrent detection  
(OCD) circuitry to identify out of range currents (OCD) with  
the result output to the fault-bar (FLT) pin. The FLT is an open  
drain, active low digital signal that is activated by the CT417  
to alert the microcontroller that a fault condition has occurred.  
• Total error output: ±1.0% FS  
• 1 MHz bandwidth  
• Response time: ~300 ns  
• UL/IEC 62368-1 and UL1577 certification  
Rated isolation voltage: 2.5 kVRMS  
Working voltage for basic isolation: 560 VRMS  
Working voltage for reinforced isolation: 280 VRMS  
• Low noise: 9.5 to 19.0 mARMS @ fBW = 100 kHz  
• Supply voltage: 3.0 to 3.6 V  
The CT417 is offered in an industry-standard 8-lead SOIC  
package that is green and RoHS compliant.  
• Filter function to reduce noise on output pin  
• Immunity to common mode fields: –40 dB  
• Overcurrent detection  
Out of range currents  
• AEC-Q100 grade 1  
APPLICATIONS  
• Solar/power inverters  
• UPS, SMPS, and telecom • Overcurrent fault protection  
power supplies  
• Motor control  
• Power utility meter  
• 8-lead SOIC package
