BOOSTING ACCURACY AND DIAGNOSTICS FOR
INVERTER AND CONVERTER APPLICATIONS
MLX91216
The MLX91216 is the IMC-Hall
®
variant of the Melexis Gen 2.5 high-speed current sensor portfolio. It introduces three
main changes over the Gen 2 MLX91208. 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 MLX91216 with the proprietary IMC-Hall
®
technology comes in the surface mount SOIC8
package and allows for a very compact and easy assembly with a shield. This IMC-Hall
®
technology provides the ultimate
equilibrium in the mechanical, electrical and magnetic requirement matching for a seamless SMT manufacturing process.

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.
