OH3141L OH44L Unipolar Hall effect IC datasheet

Product description

These Hall-effect switches are monolithic integrated circuits with tighter magnetic specifications, designed to operate continuously over extended temperatures to +150°C, and are more stable with both temperature and supply voltage changes. Each device includes a voltage regulator for operation with supply voltages of 4.5 to 24 volts, reverse battery protection diode, quadratic Hall-voltage generator, temperature compensation circuitry, small-signal amplifier, Schmitt trigger, and an open-collector output to sink up to 50 mA.

Features

• 5V to 24V DC operation voltage
• Responding to a single-pole
• Open-Collector sinking type
• 50mA maximum sinking output current
• Reverse Polarity Protection
• Good temperature performance
• Higher sensitivity
• Compatible with Digital Logic

Applications

• The brushless DC motor, DC fans, DC water pump
• The home appliance control panel
• sewing equipment, textile machinery
• speed sensor, position detecting, counting and
• The flow sensor, flow meter
• The auto-ignition, safety alarm device
• other industrial control fields
