CONVENTIONAL HALL
HIGH-SPEED CURRENT SENSOR
BOOSTING ACCURACY AND DIAGNOSTICS FOR
INVERTER AND CONVERTER APPLICATIONS
MLX91217
The MLX91217 is the Conventional Hall variant of the Melexis Gen 2.5 high-speed current sensor portfolio. It introduces
three main changes over the Gen 2 MLX91209. To serve the ever more demanding automotive application requirements,
our open-loop Hall-effect sensors are now increasing the accuracy of sensitivity and offset over temperature resulting in
market-leading sensor accuracy. Next to this improvement, the diagnostic coverage was increased with the introduction
of clamping and broken wire detection, in order to address applications with higher ASILs and/or connectors from e.g.
sensor module to control board with ECU. Finally, on-chip filtering allows for an accurate trade-off between bandwidth/
response time and higher resolution. The MLX91217 in SIP4-VA package is introduced with several Trim&Form options
to facilitate sensor integration in the air gap of the ferromagnetic core. These provide greater flexibility to designers in
the mechanical integration challenges that through-hole packages represent.

The snout of the platypus is a sensory
organ with electroreceptors in the skin
of the bill, which allow him to detect the
electrical field that gets generated when
his prey contracts its muscles. With his
40,000 sensitive electronic sensors, this
unique semi aquatic egg-laying mammal
represents our current sensors.
