• Avoids false resets due to noise with its hysteresis feature.
• Provides stable operation across a wide range of temperatures.

The S-80926CNMC-G8W-T2 voltage detector constantly monitors the input voltage. When the input voltage drops below the specified detection voltage (2.6V in this case), the device asserts a reset signal. The reset signal remains asserted until the input voltage rises above the detection voltage plus the hysteresis voltage. This hysteresis prevents the device from oscillating or generating false reset signals when the input voltage is near the threshold. The low current consumption of the device makes it ideal for battery-powered applications where power conservation is critical. The SOT-23 package allows for easy integration into space-constrained designs. The device is typically used to reset microcontrollers, CPUs, and other digital circuits to prevent malfunctions caused by voltage drops. The S-80926CNMC-G8W-T2 offers a cost-effective and reliable solution for voltage monitoring and reset generation.
