XENSIV™ TLV493D-A2BW magnetic 3D sensor with I²C interface and low power consumption The Infineon TLV493D-A2BW is a tiny magnetic 3D sensor (1.13 mm x 0.93 mm x 0.59 mm) that accurately measures x, y, and z components of a magnetic field. Its ultra-low power consumption, including 7 nA in power-down mode, significantly extends battery life in wearables and other devices. Ideal for compact wearables due to its small dimensions.
