Diodes’ AH4930Q sensor detects magnetic fields alongside the X, Y, and Z axes for contactless rotary movement and proximity sensing. As the corporate’s first automotive-compliant 3D linear Corridor impact sensor, the AH4930Q is well-suited for rotary and push selectors in infotainment techniques, stalk gear shifters, door handles and locks, and energy seat adjusters.
Certified to AEC-Q100 Grade 1, the AH4930Q operates over a temperature vary of -40°C to +125°C and integrates a 12-bit temperature sensor for correct on-chip compensation. It additionally includes a 12-bit ADC, delivering excessive decision in every measurement path, right down to 1 Gauss per bit (0.1 mT) for exact positional accuracy. An I2C interface helps knowledge studying and runtime programming with host techniques as much as 1 Mbps, enabling real-time changes.
The sensor options three working modes and a power-down mode with a consumption of simply 9 nA. Its modes stability energy and knowledge acquisition, starting from a low-power mode at 13 µA (10 Hz) to a fast-sampling mode at 3.8 mA (3.3 kHz) for steady measurement. Working with provide voltages from 2.8 V to five.5 V, the AH4930Q affords a 10-µs wake-up time, 4-µs response time, and broad bandwidth for quick knowledge acquisition in demanding functions.
Equipped in a 6-pin SOT26 package deal, the AH4930Q prices $0.50 every in numerous 1000 items.
