Infineon Technologies TLV493D 3D Sensors

Infineon TLV493D 3D Sensors provide highly accurate, three-dimensional sensing while consuming very little power. The sensors are available in small 6-pin TSOP packages. TLV493D's 3D magnetic field detection, low power consumption, high-temperature magnetic stability, and small package size helps applications become smaller, more accurate, and energy-efficient. 

Infineon offers four different derivatives: 

  • TLE493D-A2B6 (3D magnetic sensor for automotive)
  • TLE493D-W2B6 (3D magnetic sensor for automotive with wake up)
  • TLV493D-A1B6 (3D magnetic sensor for consumer)
  • TLI493D-A2B6 (3D magnetic sensor for industrial)

The Infineon Technologies TLV493D 3D Sensors' magnetic field detection senses movement in all three directions (x, y, and z) of a magnetic field. The TLV493D sensor uses lateral Hall plates to detect the z-direction. Vertical Hall plates detect the x and y directions.

Designers can set the TLV493D to perform magnetic measurements in one of five different power modes. In the ultralow-power mode, TLV493D performs a magnetic measurement every 100 milliseconds (10Hz) while only consuming 10µA of current. When using the sensor for continuous measurements, TLV493D consumes only 3.7mA (maximum) of power. In power-down mode, TLV493D only requires a 7nA supply current.

Designers can operate the TLV493D with 2.7V-3.5V supply voltages in a -40°C to +125°C temperature range. Qualified according to JESD47, the TLV493D 3D Sensor is ideal for industrial and consumer applications. Applications include joysticks, control elements in white goods, multi-function knobs, and e-meter systems that use a 3D magnetic sensor to protect against tampering.
