SGM803B Overview
The SGM803B, SGM809B and SGM810B are integrated microprocessor supervisory devices which can be reset under power-up, power-down or even voltage reduction brownout conditions. When VCC is as low as 1V, the reset output can still operate. On the power-on state, the internal timer maintains a 240ms reset assertion, which keeps the microprocessor in the reset state until the condition is stable.
