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.
The SGM803B has an active-low open-drain nRESET output. The SGM809B has an active-low push-pull nRESET output and the SGM810B has an active-high push-pull RESET output. These devices provide five reset threshold voltage options for 3V, 3.3V and 5V voltage monitoring.
The devices all have a low quiescent current of 300nA (TYP). And the glitch immunity within the reset comparator protects it from fast transients on VCC.
The SGM803B, SGM809B and SGM810B are available in Green SOT-23-3 and SOT-23 packages. They operates over a junction temperature range of -40℃ to +125℃.
