The SGM853 is a reset timer with dual voltage detector featuring low power and small solution size for applications requiring a highly integrated solution.
As a reset timer, the SGM853 has an input (RESET pin) and a fixed delay push-pull 1× output (RESET_OUT pin). It generates a low-level reset signal for 500ms (TYP) if the input has a low-level voltage for 8s (TYP). Then the reset signal returns to high for subsequent loads reset.
The SGM853 also has two voltage detector functions with 4 inputs and 2 outputs including a push-pull 1× output and a push-pull 2× output. The 2× output provides greater source and sink current. On the one side, the ALL_PG output pin indicates whether the 3 input pins (SUS_PG, VCC_PG and AUX_PG) are in a high-level voltage at the same time. If the above 3 input pins are high at the same time, the ALL_PG output pin is set to high, and vice versa. On the other side, the PROCHOT_OUT output pin generates a fixed 12ms delay time and indicates whether the PROCHOT input pin is in a high-level voltage. If PROCHOT rises to high-level voltage, PROCHOT_OUT rises after a fixed 12ms delay time, and PROCHOT_OUT falls immediately when PROCHOT falls.
The SGM853 operates over a junction temperature range of -40℃ to +125℃. It is available in a Green UTQFN-1.6×1.6-12AL package.
