SGM803B/SGM809B/SGM810B Low Power Microprocessor Supervisory Circuit GENERAL DESCRIPTION FEATURES The SGM803B, SGM809B and SGM810B are integrated ● Superior Upgrade for MAX803/MAX809/MAX810 and ADM803/ADM809/ADM810 microprocessor supervisory devices which can be reset under power-up, power-down or even voltage reduction ● High Accuracy Fixed Detection Options: 3V, 3.3V and 5V brownout conditions. When VCC is as low as 1V, the reset output can still operate. On the power-on state, ● Low Supply Current: 300nA (TYP) the internal timer maintains a 240ms reset assertion, ● 150ms (MIN) Power-on Reset Pulse Width which keeps the microprocessor in the reset state until ● Reset Output Options:  Open-Drain nRESET Output (SGM803B) the condition is stable.  Push-Pull nRESET Output (SGM809B) 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  Push-Pull RESET Output (SGM810B) ● Reset Valid Down to VCC = 1V ● Fully Specified over Temperature ● VCC Transient Immunity ● -40℃ to +125℃ Operating Temperature Range ● Available in Green SOT-23-3 and SOT-23 Packages comparator protects it from fast transients on VCC. APPLICATIONS The SGM803B, SGM809B and SGM810B are available Battery-Powered Applications in Green SOT-23-3 and SOT-23 packages. They operates over a junction temperature range of -40℃ to +125℃.

Exposure to absolute maximum rating conditions for extended periods may affect reliability. Functional operation of the device at any conditions beyond those indicated in the Recommended Operating Conditions section is not implied. ESD SENSITIVITY CAUTION This integrated circuit can be damaged if ESD protections are not considered carefully. SGMICRO recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because even small parametric changes could cause the device not to meet the published specifications.
