ULTRA-LOW CURRENT CONSUMPTION PHOTOCURRENT DETECTION IC
Rev.1.2_00
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: Micro-photocurrent detection: Wide operation voltage range: Detection of certain photocurrent level:
IDD ≤ 0.1 nA typ. IDET = 0.7 nA typ. VDD = 0.9 V to 5.5 V 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
External parts: Lead-free (Sn 100%), halogen-free*2
photodiodes (PDs) or LEDs One or two external photodiodes (PDs) or LEDs*1
*1. The required number of PDs or LEDs changes with operation. Regarding selection of PD and LED, refer to "3. Selection of PD or LED" in " Application Circuits".
*2. Refer to " Product Name Structure" for details.
