PAJ7620U2 integrates the gesture recognition function and general purpose I2C interface into a single chip. PAJ7620U2 has build in proximity sensing function that is used to detect the approaching or leaving objects. The gesture information can be easily accessed by using I2C bus


  • Typical supply voltage ranges from 2.8V to 3.3V and I/O voltage is 1.8V~3.3V
  • Nine gesture recognition (Up / Down / Left / Right / Push / Pull / CW / CCW / Wave)
  • Gesture speed is from 60°/s to 600°/s in Normal Mode and 60°/s to 1200°/s in Gaming Mode
  • Ambient light immunity: < 100k Lux
  • Built-in proximity detection
  • Flexible power saving scheme
  • I2C interface up to 400 kbit/s, Pull-up voltage from 1.8V to 3.3V
  • Ambient light noise cancellation

Introduction of Pins

VIN:Power Supply
SCL:I2C clock pin
SDA:I2C data pin
INT:Interrupt pin(Active low)


The PAJ7620U2 should be oriented as shown in Figure 4 for correct gesture detection
