Descriptions:
- The BH3548F-E2 is a unipolar Hall-effect sensor that detects the presence of a magnetic field (south pole) and provides a digital output.
- It features low power consumption and is suitable for battery-operated applications.
- The open-drain output allows easy interfacing with microcontrollers or logic circuits.
Features:
- Low Voltage Operation: Supports 2.7V to 5.5V, making it ideal for portable devices.
- High Sensitivity: Detects weak magnetic fields (±30G typical).
- Wide Temperature Range: Operates reliably from -40°C to +125°C.
- Compact Package: SIP-3 (TO-92S) for easy PCB mounting.
- Open-Drain Output: Allows flexible pull-up resistor selection.
This sensor is commonly used in position detection, proximity sensing, and speed measurement applications.
