Low Power Microprocessor Supervisory Circuit
The SGM803, SGM809 and SGM810 are integrated microprocessor supervisory devices. Compared with the design using a single IC or discrete components, this integration design has the advantage of improving system stability and accuracy.
The devices 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 that keeps the microprocessor in the reset state until the condition is stable.
The SGM803 has an open-drain RESET output that needs a resistor pulled up to VCC. The SGM809 has a push-pull RESET output. And the SGM810 has a push-pull RESET output. All devices provide eight reset threshold voltage options for 1.8V, 2.5V, 3V, 3.3V and 5V voltage monitoring.
The devices also feature excellent transient immunity to ignore fast VCC transients. Low quiescent current makes the SGM803, SGM809 and SGM810 very suitable for battery-powered applications.
The SGM803, SGM809 and SGM810 are available in Green SOT-23-3 and SOT-23 packages. They operates over an ambient temperature range of -40℃ to +125℃.
