Working Principles

The S-8244AAUFM-CEUT2U operates by continuously monitoring the input voltage (VIN). When the voltage drops below the detection threshold, the reset output (RST) is activated, indicating a low voltage condition. The built-in delay circuit ensures that the reset signal remains active for 200ms (typ.) after the voltage returns to the normal range, preventing false resets due to temporary voltage fluctuations.

Application Field Plans

The S-8244AAUFM-CEUT2U finds applications in various fields, including but not limited to: - Battery-powered devices - Portable electronics - Industrial control systems - Automotive electronics - Home appliances
