MLX91217 High Speed Current Sensor IC Datasheet are also programmable as a function of 1. Features and Benefits application needs. With the 250kHz bandwidth End-of-line programmable sensor and fast response time, it is particularly adapted for high speed applications such as inverters and Selectable analog ratiometric output converters where fast response time due to fast Measurement range from 15 to 450mT switching is required. Wideband sensing: DC to 250kHz In a typical current sensing application, the sensor Very short response time (2s) is used in combination with a ring shaped soft ferromagnetic core. This core is recommended to High linearity down to 0.2% full scale be laminated for high bandwidth applications. The Very low thermal drift MLX91217 is placed in a small air gap and the Offset drift (<5mV) current conductor a bus bar or a cable is passed through the inner part of the Sensitivity drift (<1%) ferromagnetic ring. On the one hand the ring Programmable output clamping levels concentrates and amplifies the magnetic flux seen by the sensor IC, and at the same time it Broken wire detection and diagnostics attenuates external magnetic field disturbances.

Application Examples High Voltage Traction Motor Inverter 48V Boost Recuperation Inverter DCDC Converter Smart Battery Junction Boxes Smart Fuse Overcurrent Detection Figure 1. Typical Current Sensing Application 3. Description The MLX91217 is a monolithic Hall-effect sensor which is sensitive to the flux density applied orthogonally to the IC surface. The sensor provides an analog output voltage proportional to the applied magnetic flux density. The transfer characteristic of the MLX91217 is factory trimmed over temperature, and is programmable (offset, sensitivity, clamping, filtering) during end-of-line customer calibration. Figure 2.
