MLX91206
IMC-Hall®Current Sensor (Triaxis®Technology)
2 General Description
The MLX91206 is a monolithic sensor IC featuring the Triais® Hall technology. Conventional planar Hall
technology is only sensitive to the flux density applied orthogonally to the IC surface. The IMC-Hall® current
sensor is sensitive to the flux density applied parallel to the IC surface. This is obtained through an Integrated
Magneto-Concentrator (IMC-Hall®) which is deposited on the CMOS die (as an additional back-end step).
The IMC-Hall® current sensor is automotive qualified.
The product is a single chip Hall sensor which provides an output signal which is proportional to the flux
density applied horizontally and is therefore suitable for current measurement. It is ideally used as an open
loop current sensor for PCB mounting. (see figure 2). It features small size application design and a simple
construction for various current ranges.
The transfer characteristic of the MLX91206 is programmable (offset, gain, clamping levels, diagnostic
functions…). The output is selectable between analog and PWM. The linear analog output is used for
application where a very fast response (<10 sec) is required, whereas the PWM output is used for
application where low speed but high output signal robustness is required.
