ACEINNA has announced a new current sensor designed for wideband gap (WBG) applications, which can include industrial robots and manufacturing systems, as well as home automation, appliances, motor control and DC fast charging, among others. The ±65 Amp MCx1101 Current Sensor is available in 3.3- and 5-volt versions, and units are now available for sampling and volume discounts.
THe MCx11-1’s fast response and high bandwidth is ideal for fast switching SiC and GaN-based power stages, and enables power system designers to make use of the higher speeds and smaller components enabled by WBG switches, ACEINNA said. The sensor also provides an integrated over current detection flag to help implement the Over Current Detection (OCD) required in modern power systems. Over current detection response time is 0.2us, the company added.
“ACIENNA’s MCx1101 current sensors are fully integrated, bi-directional and provide much higher DC and AC accuracy and dynamic range compared with alternative solutions,” said Teoman Ustun, vice president of marketing at ACEINNA. “For example, the new ±65 Amp versions have a typical accuracy of ±3%. This new current sensor utilizes an industry standard SOIC-16 package with a low impedance (0.9 milli-ohm) current path and are UL/IEC/EN60950-1 certified for isolated applications.”
In addition, the new current sensor combines high accuracy, 1.5MHz signal bandwidth with industry benchmark phase shift vs. frequency, fast output step response (0.3us) and 4.8kV isolation, which makes them ideal for current sensing in fast current control loops and protection for high performance power supplies, inverters, and motor control applications. In addition to the ±65Amp version, ACEINNA’s current sensor family includes ±50, ±20, and ±5 Amp ranges, and is offered in both fixed gain (MCA1101) and ratiometric gain (MCR1101) versions.
