Dual Hall-effect latch IC
MLX90224 Melexis
The MLX90224 series are dual Hall-effect latch ICs. It includes two Hall-effect latch functions of which typical thresholds are ± 2.0mT.
Top features
-
4.5 V to 26 V operation
-
Open-drain outputs
-
SIP-VA package (Through-hole)
-
Typical sensitivity ± 2 mT
-
Quadrature outputs (option A) or speed
-
Hall plate quadrature spinning current / Chopper-stabilized amplifier
Product description
The magnetic flux detection is performed through a fast circuitry, featuring a continuous offset cancellation technique (quadrature-spinning current and chopper-stabilized amplifier).
The spacing of the plates is 1.85 mm. The BOP and BRP are temperature-compensated (+500 ppm/DegC). The output refresh rate is 15 us.
The MLX90224-A quadrature outputs are latched on in the presence of a sufficiently strong South pole magnetic flux density (BOP) facing the marked side of the package. Similarly, the output are latched off in the presence of a sufficiently strong North magnetic flux density (BRP).
