Additional Details

The S-35380A-T8T1 is commonly packaged in a small SOT-25 package. The detection voltage is typically around 1.8V, indicated by the T8 in the part number, but this should be verified with the official datasheet from SII Semiconductor Corporation. It operates reliably over a wide temperature range, often between -40°C and +85°C. A pull-up resistor is required for the open-drain output to function correctly. The datasheet provides valuable information regarding recommended resistor values and operating conditions. Always consult the datasheet for accurate specifications and optimal performance.
