Description

General part information

MAX6309 Series

The MAX6305–MAX6313 CMOS microprocessor (µP) supervisory circuits are designed to monitor more than one power supply. Ideal for monitoring both 5V and 3.3V in personal computer systems, these devices assert a system reset if any of the monitored supplies falls outside the programmed threshold. Low supply current (15µA) and a small package suit them for portable applications. The MAX6305–MAX6313 are specifically designed to ignore fast transients on any monitored supply.These devices are available in a SOT23-5 package, have factory-programmed reset thresholds from 2.5V to 5.0V (in 100mV increments), and feature four power-on reset timeout periods. Ten standard versions are available. Contact the factory for availability of non standard versions.ApplicationsComputers: Desktop, Workstation, ServerControllersEmbedded Control SystemsIntelligent InstrumentsMultivoltage Systems: 3V/5V, 5V/12V, 5V/24VPortable Battery-Powered EquipmentPortable Computing
