Detailed Specifications

The S-80720AN features a detection voltage of 2.0V. It typically consumes a very small amount of current, which is essential for extending battery life in portable applications. The device also incorporates hysteresis, which prevents oscillations around the threshold voltage. It is available in a small SOT-23-5 package, making it suitable for space-constrained applications. The operating temperature range typically spans from -40°C to +85°C. The output is typically an N-channel open drain output.

The hysteresis width prevents the output from oscillating when the input voltage is near the detection threshold. This ensures clean and reliable reset signals, which are essential for the proper functioning of the system. The low current consumption contributes to extending battery life and allows the device to be used in low-power applications. The small SOT-23-5 package makes it easier to design in to small PCBs and portable devices.
