Top Features

1MHz signal path bandwidth can replace high frequency current transformers in DC/DC converters and power supplies
Lightning fast 210nS typical response time fast enough to protect IGBTs during shorting events
AEC-Q100 qualified for automotive applications up to 150C operating temperature
2400VRMS isolation rating can be used in most xEV vehicle applications with voltages as high as 420Vpk, RMS, or DC
Bidirectional and unidirectional current sensing output options can be used in full bridge or high and low side applications
Small footprint SOIC8 package can reduce PCB area over larger high frequency transformers while at the same time improving overall system quality levels
Fully integrated current sensing solution reduces overall BOM and can reduce overall system cost
1.2mOhm integrated conductor package can be used for high power density applications up to 50Amp continuous current
Integrated regulator and non-ratiometric output provide high PSRR in noisy supply environments
Integrated shield virtually eliminates capacitive coupling from current conductor to the die due to high dv/dt voltage transients
Output proportional to AC or DC current
Operation on a single 5V supply
