1. Functional Diagram
2. General Description
The MLX92213 Micropower Low-Voltage Latch Hall effect sensor IC is fabricated in mixed signal CMOS
technology. It incorporates advanced Correlated Double Sampling (CDS) techniques to provide accurate and
stable magnetic switching points. In order to save power, the internal Timing Logic alternates Awake and Sleep
modes, thus significantly reducing the power consumption. The magnetic flux density is periodically evaluated
against predefined thresholds. If the flux density is above/below the BOP/BRP thresholds, then the Output
changes its state accordingly. During the Sleep mode the Output is latched in its previous state. The design has
been optimized for applications requiring extended operating lifetime in battery-powered systems. The EN pin
adds flexibility by enabling external control of the Micropower Period and Duty Cycle. The Push-Pull Output of
the MLX92213 will be latched in Low state in the presence of a sufficiently strong South magnetic field (B > B OP
)
facing the marked side of the package. The Output will be latched in High state in the presence of a sufficiently
strong North magnetic field (B < BRP).
