... Rev 6; 7/12 General Description 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 (15µ ...

... MAX6312/MAX6313 also monitor V CC trimmed resistor divider to the reset comparator. A µP’s reset input starts the µ known state. These µP supervisory circuits assert reset to prevent code- execution errors during power-up, power-down, or brownout conditions. RESET (MAX6305–MAX6310) and RESET (MAX6311/ ...
