The BH3548F-E2 is a Hall-effect sensor manufactured by ROHM Semiconductor. Below are its key specifications, descriptions, and features:

Specifications:

• Type: Hall-effect sensor (unipolar)
• Operating Voltage (VDD): 2.7V to 5.5V
• Output Type: Open-drain (N-channel MOSFET)
• Operating Temperature Range: -40°C to +125°C
• Magnetic Sensitivity (BOP/BRP): Typically ±30G (Gauss)
• Hysteresis (BHYS): Typically ±10G
• Output Current (IOUT): 25mA (max)
• Package: SIP-3 (TO-92S)

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.
