APX9031
Hall Effect Sensor IC
Features
• •
On-chip Hall Sensor Low Operating Supply Voltage : 3 V with Reverse Voltage Protection
General Description
The APX9031 is an integrated Hall Effect Sensor IC designed for electric commutation of DC brushless motor applications. Even with a reverse voltage protection diode, the APX9031 still can operate at as low as 3 volts. The APX9031 is available in low cost TO-92M3 and SOT-89 packages with 3 different magnetic ranks.
• Versatile sensitivity and hysteresis setting • Reliable and Rugged • TO-92M3 and SOT-89 packages
