MAX6797ADual/Triple, Ultra-Low-Voltage, SOT23 µP Supervisory Circuits | Supervisors | 1 | Active | The MAX6715A–MAX6729A/MAX6797A are ultra-low-voltage microprocessor (µP) supervisory circuits designed to monitor two or three system power-supply voltages. These devices assert a system reset if any monitored supply falls below its factory-trimmed or adjustable threshold and maintain reset for a minimum timeout period after all supplies rise above their thresholds. The integrated dual/triple supervisory circuits significantly improve system reliability and reduce size compared to separate ICs or discrete components.These devices monitor primary supply voltages (VCC1) from 1.8V to 5.0V and secondary supply voltages (VCC2) from 0.9V to 3.3V with factory-trimmed reset threshold voltage options (see theReset Voltage Threshold Suffix Guidein the full data sheet). An externally adjustable RSTIN input option allows customers to monitor a third supply voltage down to 0.62V. These devices are guaranteed to be in the correct reset output logic state when either VCC1or VCC2remains greater than 0.8V.A variety of push-pull or open-drain reset outputs along with watchdog input, manual-reset input, and power-fail input/output features are available (see theSelector Guidein the full data sheet). Select reset timeout periods from 1.1ms to 1120ms (min) (see theReset Timeout Period Suffix Guidein the full data sheet). The MAX6715A–MAX6729A/MAX6797A are available in small 5-, 6-, and 8-pin SOT23 packages and operate over the -40°C to +125°C temperature range.ApplicationsComputers/ServersIndustrial EquipmentMultivoltage SystemsPortable Battery-Powered EquipmentPrinters/Fax MachinesSet-Top BoxesTelecom/Networking Equipment |

MAX68003-Pin, Low-Power µP Reset Circuits | PMIC | 12 | Active | The MAX6800/MAX6801/MAX6802 microprocessor (µP) supervisory circuits monitor the power supplies in 2.85V to 5.0V µP and digital systems. They increase circuit reliability and reduce cost by eliminating external components and adjustments.These devices perform a single function—they assert a reset signal whenever the VCCsupply voltage declines below a preset threshold, keeping it asserted for a preset timeout period after VCChas risen above the reset threshold. The only difference among the three devices is their output. The MAX6801 (push/pull) and MAX6802 (open-drain) have an active-low RESET output, while the MAX6800 (push/pull) has an active-high RESET output. The MAX6800/MAX6801 are guaranteed to be in the correct state for VCCdown to 0.7V. The MAX6802 is guaranteed to be in the correct state for VCCdown to 1.0V.The reset comparator in these ICs is designed to ignore fast transients on VCC. Reset thresholds are factory-trimmable between 2.63V and 4.80V, in approximately 100mV increments. These devices are available with a 1ms (min), 20ms (min), or 100ms (min) reset pulse width. Ideal for space-critical applications, the MAX6800/MAX6801/MAX6802 come packaged in a 3-pin SOT23.
