S-5470

S-5470 Series www.sii-ic.com © Seiko Instruments Inc., 2012 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.
