OH137A0 OH17 Bipolar Hall IC Datasheet

Product description

OH137A0, OH17 bipolar IC response to an N/S alternative magnetic field. Each device includes an on-chip Hall voltage generator for magnetic sensing, an amplifier that amplifies the Hall voltage, a Schmitt trigger to provide switching hysteresis for noise rejection, and open-collector output.

Features

• 4.5V to 24V DC operation voltage
• Open-Collector pre-driver
• 25mA maximum sinking output current.
• Reverse Polarity Protection

Applications

• Position detection
• Flow measurement
• CPU FAN
