Melexis has introduced the MLX91235, a new current sensor that eliminates the need for a ferromagnetic core. The MLX91235 expands Melexis’ portfolio, enabling the measurement of larger currents flowing through external primary conductors like PCB traces and busbars. It supports automotive and alternative mobility applications like inverters, battery management systems (BMSs) and low-voltage DC-DC converters.
Power electronic designers are constantly faced with the challenge of system size and weight in modern electric vehicles (EVs), resulting in an ongoing demand for smaller and lighter solutions. By eliminating the ferromagnetic concentrator, the gradiometric MLX91235 achieves a significantly smaller footprint than typical current sensor technologies and eliminates hysteresis-related measurement errors.
