MLX90377 - Triaxis® Position Sensor IC Datasheet
2022-06-29
●Description
■The MLX90377 is a monolithic magnetic position sensor IC.It consists of a Triaxis® Hall magnetic front end, an analog to digital signal conditioner,a DSP for advanced signal processing and an output stage driver.
■The MLX90377 is sensitive to the three components of the magnetic flux density applied to the IC (i.e. Bx,By and Bz).This allows the MLX90377with the correct magnetic circuit to decode the absolute position of any moving magnet (e.g.rotary position from 0 to 360 Degrees or linear displacement,see Figure 2).It enables the design of non-contacting position sensors that are frequently required for both automotive and industrial applications.
■The MLX90377 provides 4 output modes.Firstly,the IC supports (fast) SENT and SPC frames encoded according to a Secure Sensor format.The output delivers enhanced serial messages providing error codes,and user-defined values.Through programming,the MLX90377 can also be configured to output a PWM (Pulse Width Modulated) signal.Finally,analog ratiometric output is also supported.
●Features and Benefits
■Triaxis® Hall Technology
■On Chip Signal Processing for Robust Absolute Position Sensing
■Programmable Measurement Range
■Programmable Linear Transfer Characteristic (4 or 8 Multi-points or 16 or 32 Piece-Wise-Linear)
■Selectable (fast) SENT,PWM,SPC or Ratiometric Analog Output modes
■SAE J2716 APR2016 SENT
■ISO26262 ASIL-C capable for (fast) SENT,PWM,SPC Output modes,and ASIL-B capable for analog output mode,Safety Element out of Context
■Enhanced serial data communication
■48 bit ID Number option
■Single Die-SOIC-8,DMP-4,SMP-3,and Dual Die (Full Redundant)-TSSOP-16 package RoHS Compliant
■Robustness against stray-field
