Working Principles

The S-8250BAE-I6T1U operates by continuously monitoring the input voltage using an internal voltage reference. When the input voltage falls below the detection threshold, the reset output is activated after a programmable delay. This delay is determined by the external capacitor connected to the CT pin. The IC remains in a low-power state during normal operation, consuming minimal current.
