Diodes launched its first automotive-compliant 3D linear Hall effect sensor, the AH4930Q. This innovative sensor is designed to deliver reliable and high-precision contactless rotary motion and proximity detection, making it ideal for a wide range of automotive applications. The AH4930Q is capable of detecting magnetic fields in the X, Y, and Z directions, providing exceptional accuracy and reliability. This makes it perfect for use in rotary and push selectors on infotainment systems, stalk gear shifters, door handles and locks, and powered seat adjusters.
Key features:
12-bit Temperature Sensor: Ensures accurate on-chip compensation for precise measurements.
High Resolution: The robust signal path and 12-bit data converter via ADC offer high resolution for each measurement direction down to 1 Gauss (0.1mT) per bit.
I2C Interface: Enables seamless communication for measurement data reading and runtime programming with host systems at speeds up to 1Mbps, supporting real-time adjustments.
Multiple Operating Modes: Includes three operating modes plus a power-down mode with ultra-low power consumption of only 9nA. The ultra-low-power mode consumes just 13μA (10Hz), while the fast-sampling mode consumes 3.8mA (3.3kHz) for constant measurement functionality.
Fast Data Acquisition: With a 10μs wake-up time, 4μs response time, and wide bandwidth, the AH4930Q delivers ultra-fast data acquisition for demanding applications.
Wide Operating Range: Operates on supply voltages from 2.8V to 5.5V and a temperature range from -40°C to +125°C.
Potential Applications:
Infotainment Systems: Rotary and push selectors for user interface controls.
Stalk Gear Shifters: Precise detection of gear positions.
Door Handles and Locks: Contactless detection for enhanced security and convenience.
Powered Seat Adjusters: Accurate position sensing for seat adjustments.
Electronic Throttle Control: Precise measurement of throttle position.
Steering Angle Sensors: Accurate detection of steering wheel position.
Brake and Accelerator Pedal Positioning: Reliable detection of pedal positions for improved vehicle control.
