Pinout
The SGM811-RXKA4/TR is a voltage supervisor or reset IC, typically used to monitor the power supply voltage in microcontroller and microprocessor systems to ensure they operate correctly when powering up or down. It comes in a small SOT-143 package with 4 pins.
The pin configuration is generally as follows:
1. GND: Ground.
2. VCC: Supply voltage input, where the monitored voltage is applied.
3. RESET: This is an output pin. It is used to reset the microcontroller or microprocessor. The RESET pin goes low when VCC falls below the threshold and remains low for a certain delay after VCC exceeds the threshold voltage again.
4. NC (No Connection): This pin is not connected internally and is typically left unconnected.
