Melexis MLX90423 Triaxis® Magnetic 3D Position Sensors

Melexis MLX90423 Triaxis® Magnetic 3D Position Sensors consist of a Triaxis Hall magnetic front end, an analog-to-digital signal conditioner, a DSP for advanced signal processing, and a programmable output stage driver (analog, PWM, or SENT). Supporting an operating temperature up to +160°C, the linear stray field immune MLX90423 components provide superior capabilities in terms of functional safety, absolute maximum ratings (AMR), and electromagnetic compliance (EMC) characteristics. The Melexis MLX90423 sensors are designed for cost-sensitive automotive applications, including powertrain actuators, pedal positioning, fuel level gauges, and transmission systems. These devices are also suitable for industrial implementations.
