DIODES INC. AH1897SFAN7 Omnipolar Hall Switch

The AH1897S is a low power omnipolar Hall-effect switch IC designed for portable devices like cellular phones and tablets. It operates over a supply voltage range of 1.6V to 3.6V, drawing only 4.3µA at 1.85V, making it ideal for battery-powered applications. The device features internal pull-up and pull-down capabilities, with a small low-profile X1-DFN1216-4 package. It detects magnetic fields from either pole, switching on when B exceeds the operate point and off when below the release point. Suitable for cover, display, or holster detection, it provides reliable RF noise immunity, excellent temperature stability, and is fully lead-free and RoHS compliant.
