The SGM809B-TXN3G/TR is a 3-pin microprocessor reset IC with the following functions:
1. VCC (Pin 1) – Power supply input (1.1V to 5.5V).
2. GND (Pin 2) – Ground connection.
3. RESET (Pin 3) – Active-low open-drain output, asserts low when VCC drops below the threshold (~2.93V typical).
It provides power-on reset (POR) and brown-out reset (BOR) functions, ensuring reliable system initialization. The open-drain output requires an external pull-up resistor.
Package: SOT-23-3.
