Melexis MLX91235
The MLX91235 is a smart high-speed, current sensor IC with built-in stray field immunity, de-signed for measuring current in an external conductor. This conductor can be either a busbar or a PCB trace. It needs to adopt a special shape to generate a gradient magnetic field on the sensor, typically a neckdown is recommended.| Part No. | MLX91235 |
