Infineon Technologies 3D hall sensors - TLV493D

The TLV493D-A2BW is a magnetic 3D sensor that offers accurate three-dimensional sensing with extremely low power consumption. Within its small WLB package, the sensor provides direct measurement of the x, y, and z components of a magnetic field. The newly released TLV493D-A2BW has the halogen-free package and ultra-small size that provides more flexibility to end customer for designing.

Key features

• 3D (X, Y, Z) magnetic flux density sensing up to ±160 mT
• Programmable sensitivity up to typ. 30.8 LSB 12/mT
• Extremely small form factor: typ. 1.13 mm x 0.93 mm x 0.59 mm
• Power down mode with 7 nA (typ.) power consumption

Additional features

• 12-bit data resolution for each measurement direction plus 10-bit temperature sensor
• Variable update frequencies and power modes (configurable during operation)
• Temperature range Tj = -20 °C to 85 °C
• Supply voltage range = 2.8 V to 3.5 V
• Triggering by external microcontroller possible via I2C protocol
