Surface-mount SO8 isolated current transducers, to 20A

The GHS series of miniature, integrated circuit transducers are for AC and DC isolated current measurement up to 100 kHz. These new components offer full 2 kV isolation despite their small size, integrating the primary conductor for nominal current measurements of 10A, 12A, 16A or 20A with a measurement span of 2.5 times the nominal current, they are also able to support high overload currents up to 200A peak for short durations (1 msec).


The transducers are directly PCB mounted and integrate the primary conductor path while still providing high creepage and clearance distances. All the models provide a ratiometric analogue voltage output with different sensitivity levels from 40 to 80 mV/A according to the model, with a typical response time of 5 µsec.


The GHS series has been designed with unique primary integrated conductors for gradient measurement to provide an excellent immunity against the external fields found in power electronic applications. Programmable internal temperature compensation uses EEPROM parameter storage, ensuring high performance accuracy over the full range of temperature with a maximum 1.3 % offset drift and 1.5 % gain drift. The GHS series operates from a single 5 V supply and over a wide operating temperature range from -40 to +125°C.
