Ultra-low Current Consumption Photocurrent Detection IC S-5470 Series

The S-5470 Series, developed by CMOS technology, is a photocurrent detection IC with an ultra-low current consumption.
It detects 0.7 nA typ. photocurrent generated by an external photodiode (PD) or LED. It also has a function to detect the difference of photocurrent level between two external photodiodes (PDs) or LEDs.
Due to its ultra-low current consumption and low-voltage operation, the S-5470 Series is suitable for battery-operated small mobile device applications.

Features

  • Ultra-low current consumption: IDD = 0.1 nA typ.
  • Micro-photocurrent detection: IDET = 0.7 nA typ.
  • Wide operating voltage range: VDD = 0.9 V to 5.5 V
  • Detection of certain photocurrent level: Detects certain level of photocurrent generated by external photodiode (PD) or LED
  • Detection of photocurrent level difference: Detects the difference of photocurrent level between external photodiodes (PDs) or LEDs
  • External parts: One or two external photodiodes (PDs) or LEDs*1
  • Lead-free (Sn 100%), halogen-free
  • Package: SOT-23-5

    • *1. The required number of PDs or LEDs changes with operation.

    Applications

  • Shading detection
  • Light and darkness detection
  • Non-contact switch for portable and wireless device
