Working Principles
The STM705DS6E is a voltage supervisor IC that ensures proper operation of electronic systems by monitoring the supply voltage. It compares the supply voltage with a user-adjustable threshold voltage. When the supply voltage falls below the threshold, the reset output is asserted, indicating a power failure or an out-of-range condition. The reset signal remains active until the supply voltage rises above the threshold and the reset timeout period elapses.
