TLV493D-A2BW high accuracy, low power
Overview
XENSIV™ - TLV493D-A2BW magnetic 3D sensor with extremely low power consumption and halogen free package
The Infineon TLV493D-A2BW is a magnetic 3D sensor that offers accurate three dimensional sensing with extremely low power consumption. Within its small WLB package (1.13 mm x 0.93 mm x 0.59 mm) the sensor provides direct measurement of the x-, y-, and z components of a magnetic field.
The extremely small dimensions enables the usage in wearable or similar devices. The extremely low quiescent current (7 nA in power-down mode) extend battery life time or battery charging cycles.
Summary of Features
