• 商品描述： 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 V CC 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 V CC . 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 ℃ .
