Product Overview
The SC4391 is a high-speed linear Hall sensor IC featuring configurable digital output and a wake-up function. It integrates a magnetic sensing element and a high-precision ADC sampling module to accurately convert external magnetic field variations into digital signals. With configurable registers, users can adjust sensitivity and static output voltage to meet diverse application requirements. The chip supports multiple operating modes, including a low-power mode with a wake-up feature, catering to different speed and power consumption needs. It communicates via an 8MHz SPI interface and supports daisy-chain connections for multi-point detection. Available in SOT23-6L and DFN2*2-8L packages, the SC4391 is designed for analog magnetic keyboards, touch switches, magnetic silent switches, and joystick applications.
