Melexis MLX92217 Hall-Effect Switches

Melexis MLX92217 Hall-Effect Switches are monolithic magnetic sensors utilizing Hall-effect sensor technology. The switches feature integrated logic for automatic Sleep/Awake sequencing, which enables 1μA average current consumption without user action. The Melexis MLX92217 Hall-effect Switches offer selective functions, including magnetic thresholds, magnetic functions, and sleep times. The switches are ideal for reed switch replacement, open/close detection, proximity sensor, and other applications.
