S-5470 Series ULTRA-LOW CURRENT CONSUMPTION www.ablic.com NORMALLY-OFF FAINT SIGNAL DETECTION IC www.ablicinc.com ABLIC Inc., 2012-2016 Rev.1.3 02 The S-5470 Series, developed by CMOS technology, is a normally-off faint signal detection IC with an ultra-low current consumption. This IC has a function to detect certain current level of 0.7 nA typ., which makes it possible to detect faint signals for a variety of electric generating devices or sensor devices. It also has a function to detect the difference of current level, and thus detects difference between strengths of two signals input at the same time. 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: I 0.1 nA typ. DD Faint current detection: I = 0.7 nA typ. DET Wide operation voltage range: V = 0.9 V to 5.5 V DD Detection of faint signal: Detects faint signals of approximately 0.7 nW (1.0 V, 0.7 nA typ.) Detection of signal strength difference: Detects difference between strengths of two signals input at the same time Lead-free (Sn 100%), halogen-free Applications Detects output signals of electric generating devices or sensor devices with high internal resistance Advanced sensing using two electric generating devices or sensor devices Miniaturization and low power consumption for various sensors of portable and wireless devices Package SOT-23-5 1 ULTRA-LOW CURRENT CONSUMPTION NORMALLY-OFF FAINT SIGNAL DETECTION IC S-5470 Series Rev.1.3 02 Block Diagrams 1.
