The VCNL36825T integrates a proximity sensor (PS), and a VCSEL into one small package. It incorporates photodiodes, amplifiers, and analog to digital converting circuits into a single chip by CMOS process. PS programmable interrupt features of individual high and low thresholds offers the best utilization of resource and power saving on the microcontroller.

Key features

  • Integrated modules: VCSEL, proximity sensor (PS), and signal conditioning IC
  • Low power consumption I2C (SMBus compatible interface)
  • 1.6 mm single hole opening design
  • Temperature compensation: -40 °C to +85 °C

Additional features

  • Package type: surface-mount
  • Dimensions (L x W x H in mm): 2.0 x 1.25 x 0.5
  • Integrated modules:
    • Vertical-cavity surface-emitting laser (VCSEL)
    • Proximity sensor (PS)
    • Signal conditioning IC
  • Interrupt function
  • 1.6 mm single hole opening design
  • Supply voltage range VDD: 2.64 V to 3.6 V
  • Low power consumption I2C (SMBus compatible interface)
  • Interface: I2C bus
  • Temperature compensation: -40 to +85 °C
  • Floor life: 168 h, MSL 3, according to J-STD-020
  • Proximity functions:
    • Immunity to red glow (940 nm IRED)
    • Programmable IVCSEL sink current
    • Intelligent cancellation to reduce cross-talk phenomenon
    • Smart persistence scheme to reduce PS response time
    • Low power consumption mode
    • Sunlight cancellation up to 100 klx
  • Interrupt:
    • Programmable interrupt function for PS with upper and lower thresholds
    • Adjustable persistence to prevent false triggers for PS
