      ADM811LARTZ-REEL
      GENERAL DESCRIPTIONThe ADM811/ADM812 are reliable voltage monitoring devices suitable for use in most voltage monitoring applications. The ADM811/ADM812 are designed to monitor six different voltages, each allowing a 5% or 10% degradation of standard PSU voltages before a reset occurs. These voltages have been selected for the effective monitoring of 2.5 V, 3 V, 3.3 V, and 5 V supply voltage levels.FEATURESSuperior upgrade for MAX811/MAX812Specified over temperatureLow power consumption: 5 µA typicalPrecision voltage monitor: 2.5 V, 3 V, 3.3 V, 5 V optionsReset assertion down to 1 VCCPower-on reset: 140 ms minimumLogic low RESET output (ADM811)Logic high RESET output (ADM812)Built-in manual resetAPPLICATIONSMicroprocessor systemsControllersIntelligent instrumentsAutomotive systemsSafety systemsPortable instruments

      ADM809ZARTZ-REEL7
      GENERAL DESCRIPTIONThe ADM803/ADM809/ADM810 supervisory circuits monitor the power supply voltage in microprocessor systems. They provide a reset output during power-up, power-down, and brownout conditions. On power-up, an internal timer holds reset asserted for 240 ms. This holds the microprocessor in a reset state until conditions have stabilized. The reset output remains operational with VCC as low as 1 V. The ADM803 and ADM809 provide an active low reset signal (RESET), whereas the ADM810 provides an active high signal (RESET) output. The ADM809 and ADM810 have push-pull outputs, whereas the ADM803 has an open-drain output, which requires an external pull-up resistor.FEATURESSpecified over temperatureLow power consumption: 17 μAPrecision voltage monitor: 2.5 V, 3 V, 3.3 V, 5 V optionsReset assertion down to 1 V VCC140 ms minimum power-on resetOpen-drain RESET output (ADM803)Push-pull RESET output (ADM809)Push-pull RESET output (ADM810)SC70 and SOT-23 packagesAPPLICATIONSMicroprocessor systemsComputersControllersIntelligent instruments

      ADM1815-R22ART-RL7
      GENERAL DESCRIPTIONThe ADM181x range of voltage monitoring circuits can be used in any application where an electronic system needs to be reset when a voltage increases above or below a predetermined value.Because of the reset delay time incorporated into the ADM181x series, these devices can provide a safe startup for electronic systems. Before a system initializes, the power supply must stabilize. Using the ADM181x series ensures that there are typically 150 ms for the power supply to stabilize before the system is reset and safe system initialization begins.The ADM181x series of microprocessor reset circuits are available in low cost, space-saving SOT-23 packages.FEATURESReliable Low Cost Voltage Monitor with Reset OutputSuitable for Monitoring 2.5 V, 3 V, 3.3 V, and 5 V PowerSupply VoltagesReset Threshold Levels: 4.62 V, 4.35 V, 3.06 V, 2.88 V,2.55 V, 2.31 V, and 2.18 V (Typ)Active High and Low Push-Pull Output Choices(ADM1810, ADM1812, ADM1815, and ADM1817)Open-Drain Output Choices (ADM1811, ADM1813,ADM1816, and ADM1818)Can Be Used with a Manual Push-Button to Generatea Reset (ADM1813, ADM1818)Initialize Microprocessor Systems with Added SafetyAvailable in a 3-Lead SOT-23 PackageAPPLICATIONSMicroprocessor SystemsComputersControllersIntelligent InstrumentsAutomotive Systems

      ADM8616RCYAKSZ-RL7
      GENERAL DESCRIPTIONThe ADM8611/ADM8616/ADM8617/ADM8618 are supervisory circuits which monitor power supply voltage levels and code execution integrity in microprocessor-based systems. A power-on-reset signal is generated when the supply voltage rises to a preset threshold level. The ADM8611’s debounced manual reset input can be used to initiate a reset by means of an external push-button or logic signal. The ADM8616–ADM8618 have an on-chip watchdog timer which can reset the microprocessor if it fails to strobe within a preset timeout period.FEATURESPrecision 1.8V to 5V Power Supply Monitoring9 Reset Threshold Options:1.58V to 4.63V140ms (Min) Reset TimeoutManual Reset Input (ADM8611)Watchdog Timer (ADM8616–ADM8618)Reset Output StagesPush-Pull Active-LowOpen-Drain Active-LowPush-Pull Active-HighLow Power Consumption (3µA)Guaranteed Reset Output valid to VCC=1VPower Supply Glitch ImmunitySpecified Over -40°C to +85°C Temperature Range4-Lead SC70 PackageAPPLICATIONSMicroprocessor SystemsComputersControllersIntelligent InstrumentsPortable Equipment

      GENERAL DESCRIPTIONThe ADM6821-ADM6825 are supervisory circuits which monitor power supply voltage levels and code execution integrity in microprocessor-based systems. As well as providing power-on-reset signals, an on-chip watchdog timer can reset the microprocessor if it fails to strobe within a preset timeout period. A reset signal can also be asserted by means of an external push-button, through a manual reset input. The three parts feature different combinations of watchdog input, manual reset input and output stage configuration, as shown in table 1.FEATURESPrecision Low Voltage Monitoring down to 1.8V9 Reset Threshold Options:1.58V to 4.63V140ms (Min) Reset TimeoutWatchdog Timer with 1.6s TimeoutManual Reset InputReset Output StagesPush-Pull Active-LowOpen-Drain Active-LowPush-Pull Active-HighLow Power Consumption (3µA)Guaranteed Reset Output valid to VCC=1VPower Supply Glitch ImmunitySpecified from -40°C to +125°C5-Lead SOT-23 PackageAPPLICATIONSMicroprocessor SystemsComputersControllersIntelligent InstrumentsPortable Equipment
