Micronas has introduced the novel CUR 3150 and CUR 3155 Hall-effect current sensing devices under its CUR 315x product series portfolio.
The programmable devices generate digital output in the form of a PWM signal with a maximum resolution of 16 bits. The CUR 3150 and CUR 3155 systems utilize active compensation for providing precise calibrations. They are capable of reducing sensitivity errors on temperature leading to a value lower than 1 % under optimum environments.
The current sensors can be deployed for monitoring current in batteries in hybrid as well as electric vehicles, intelligent metering, start-stop systems, and solar inverters.
According to the company, a ferromagnetic flux concentrator when coupled with the CUR 315x series detects electric currents in milliampere. By employing a unique conductor design, heavy current range measurements can be executed without flux concentrator. The bandwidth attains more than 2 kHz with programmable magnetic field in the range of ±20 to ±160 mT.
The CUR 315x series is available with TO92UT enclosure which can be welded or soldered. This series also features a thermal range of TJ = -40 °C to 140 °C, with the identification of overvoltage and reverse voltage shielding of the supply interface.
