Hall-effect switch - ultra low power consumption for automotive - MLX92235
Product description
The MLX92235 is an ultra low power Hall-effect switch with best-in-class tolerances for reliable and predictable output update rate. This automotive tiny device is made for micropower open-close detection.
The MLX92235 has an integrated logic for automatic Sleep/Awake sequencing enabling 1μA average current consumption without any action from the user (depending on the selected product). During the Awake state the chip is comparing the applied magnetic field to the predefined magnetic thresholds and updates its output accordingly. During Sleep state the OUT state remains unchanged regardless of the magnetic field. The OUT state will be refreshed during the next Awake period. The MLX92235 can be selected with various functions: magnetic thresholds, magnetic functions and sleep times.
This versatile Hall-effect switch serves as a general replacement for reed switches, offering enhanced solid-state reliability. The MLX92235 is particularly well-suited for battery-powered devices, lid open/close detection, wake-up switches, and other low-voltage applications where minimizing current consumption is critical.
Application examples
- Brake light/ wake-up switch
- E-Latch / e-door Handle
- Sunvisor / Vanity Mirror
- Button / HMI / Levers
- Seat positioning / folding
- Proximity sensor, Reed switch replacement, open/close detection
