• Limited Input Voltage Range: The S-8211CDH-I6T1U is designed to operate within a voltage range of 1.6V to 6.0V, which may not be suitable for applications requiring higher or lower voltages.
• Single Reset Output: This IC provides only one reset output, limiting its use in systems that require multiple reset signals.

Working Principles

The S-8211CDH-I6T1U operates by continuously monitoring the input voltage using an internal voltage detection circuit. When the voltage drops below a predetermined threshold, the delay circuit activates, introducing a delay time before generating a reset signal. This delay prevents false resets caused by temporary voltage fluctuations. Once the input voltage is restored, the reset output becomes active low, signaling the system to reset.
