OH543 Overview
OH543，OH443, OH443R series unipolar hall IC 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. It detects the changes of the Magnetic field and outputs a digital voltage signal.
OH543 Key Features
- 3.8V to 30V DC operation voltage
- Open-Collector sinking type
- 50mA maximum sinking output current
- Reverse Polarity Protection
- Good temperature performance
