... General Description The MIC2777 is a dual power supply supervisor that provides under-voltage monitoring, manual reset capability, and power- on reset generation in a compact 5-pin SOT package. Fea- tures include two under-voltage detectors, one fixed and one adjustable, and both active-high and active-low reset outputs. ...

... Typically, the MIC2777 is used to monitor the power supplies of intelligent circuits such as microcontrollers and micropro- cessors. By connecting the appropriate reset output MIC2777 to the reset input of a µC or µP, the processor will be properly reset at power-on and during power-down and will fall below IN brown-out conditions. ...

... – R2 TOTAL Application Example Figure 1 illustrates a hypothetical MIC2777-23 application in which the MIC2777-23 is used to monitor the core and I/O supplies of a high-performance CPU or DSP. The core supply this example is 1.0V ±5%. The main power CORE rail and I/O voltage 2.5V ±5%. As shown in Figure 1, ...

... The resistor’s value is not critical, however. See Figure 3. The statements above also apply to the MIC2777’s RST out- put. That is, to ensure valid RST signal levels pull-up resistor (as opposed to a pull-down) should be added to the RST output. A value of 100kΩ ...
