The MAX6316–MAX6322 family of microprocessor (µP) supervisory circuits monitors power supplies and microprocessor activity in digital systems. It offers several combinations of push/pull, open-drain, and bidirectional (such as Motorola 68HC11) reset outputs, along with watchdog and manual reset features. TheSelector Guidebelow lists the specific functions available from each device.These devices are available in 26 factory-trimmed reset threshold voltages (from 2.5V to 5V, in 100mV increments), featuring four minimum power-on reset timeout periods (from 1ms to 1.12s), and four watchdog timeout periods (from 6.3ms to 25.6s). Thirteen standard versions are available with an order increment requirement of 2500 pieces (seeStandard Versionstable in the full data sheet); contact the factory for availability of other versions, which have an order increment requirement of 10,000 pieces.The MAX6316–MAX6322 are offered in a miniature 5-pin SOT23 package.ApplicationsComputersControllersEmbedded Control SystemsIntelligent InstrumentsPortable Battery-Powered EquipmentPortable Computers

The MAX6325/MAX6341/MAX6350 are low-noise, precision voltage references with extremely low, 0.5ppm/°C typical temperature coefficients and excellent, ±0.02% initial accuracy. These devices feature buried-zener technology for lowest noise performance. Load-regulation specifications are guaranteed for source and sink currents up to 15mA. Excellent line and load regulation and low output impedance at high frequencies make them ideal for high-resolution data-conversion systems up to 16 bits.The MAX6325 is set for a 2.500V output, the MAX6341 is set for a 4.096V output, and the MAX6350 is set for a 5.000V output. All three provide for the option of external trimming and noise reduction.ApplicationsAutomated Test Equipment (ATE)Digital VoltmetersHigh-Accuracy Industrial and Process ControlHigh-Accuracy Reference StandardHigh-Resolution A/D and D/A ConvertersPrecision Current Sources
