Hall-effect magnetic sensor - Low power consumption
MLX92213 Melexis
The MLX92213 features an ultra-sensitive Hall-effect latch operating from 1.6 V to 3.6 V. The output is a Push-Pull type so that an external pull-up resistor is not needed for proper operation, hence reducing PCB component count.

Hall-effect magnetic sensor - Low power consumption - MLX92213
Product description
This device is primarily targeting battery-operated applications. As the famous Hall-effect omnipolar switch MLX90248, the MLX92213 employs an awake/sleep strategy to reduce its power consumption versus a standard Hall-effect latch sensor.
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 MLX92213 provides also a dedicated "enable" pin, adding flexibility by enabling external control of the micropower period and duty cycle. Driving the enable pin to low state, the device enters into a standby mode with an ultra-low current consumption. The device can therefore be virtually switched off with a simple logical signal to save even more power.
The Push-Pull output of the MLX92213 will be latched in low state in the presence of a sufficiently strong South magnetic field (B > BOP) 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).
This micropower Hall-effect latch is an ideal solution for use in speed and direction detection application based on multi-pole magnet assembly for portable or low-power devices.
The MLX92213 device is delivered in a lead-free and green compliant Micro Leadframe Package (MLP). This miniature package requires only 3 mm² PCB surface (1.5 mm x 2 mm) with only 0.4 mm thickness.
