... A reset can be generated at any time by asserting the manual reset input, /MR. This reset output will remain active at least 140ms after the release of /MR. The /MR input can also be used to daisy-chain the MIC2775 onto existing power monitoring circuitry or other supervisors. Hysteresis is included to prevent chattering due to noise. ...

... Typically, the MIC2775 is used to monitor the power supply of intelligent circuits such as microcontrollers and micropro- cessors. By connecting the appropriate reset output of a MIC2775 to the reset input of a µC or µP, the processor will be properly reset at power-on and during power-down and brown-out conditions. In addition, asserting /MR, the manual reset input, will activate the reset function ...

... DD not turn on sufficiently to produce a valid logic-low on /RST. In this situation, circuits driven by /RST could be allowed to float, causing undesired operation. (In most cases, however expected that the circuits driven by the MIC2775 will be similarly inoperative at V ≤ 1.2V given application requires that /RST be valid below V = 1.2V, this can be accomplished by adding a pull-down re- sistor to the /RST output. A value of 100kΩ ...
