                                                                                                    AH1912-W-7 is an ultra-low-power digital omnipolar hall effect switch IC. The wider range of supply voltage (1.6V to 5.5V) extends battery operating time and supports low-voltage system microcontrollers, which provides great flexibility for system design. The advanced chopper stabilized design provides superior stability on the switch operating point over temperature and supply voltage. When the magnetic flux density (B) perpendicular to the package is larger than operate point (BOP), the output will be turned on (pulled low) and held until B is lower than the release point (BRP). Applications include smart cover or dock detect for cellular phones and tablet PCs, gas or water consumption measurement in remote, battery-operated utility meters, medical devices, IoT systems, level, proximity and position switches, E-locks, smoke detectors, and appliances.
