元器件交易网-Power, Single/Dual-Voltage µP Reset Circuitswith Capacitor-Adjustable Reset Timeout DelayMAX6412–MAX6420Use the following formula to calculate the externallymonitored voltage (VMON_TH):VMON_TH= VRST✕(R1 + R2)/R2where VMON_THis the desired reset threshold voltageand VRSTis the reset input threshold (1.26V). ResistorsR1 and R2 can have very high values to minimize cur-rent consumption due to low leakage currents. Set R2to some conveniently high value (1MΩ, for example)and calculate R1 based on the desired monitored volt-age, using the following formula:

R1 = R2 x (VMON_TH/VRST- 1) (Ω)VCCR1RESET INR2GNDVCCMAX6415–MAX6420Manual Reset Input(MAX6412/MAX6413/MAX6414)Many µP based products require manual reset capabil-ity, allowing the operator, a technician, or external logiccircuitry to initiate a reset.

Connect a normally openmomentary switch from MRto ground to create a man-ual reset function (external debounce circuitry is notrequired for long reset timeout periods).A manual reset option can easily be implemented with theMAX6415–MAX6420 by connecting a normally openmomentary switch in parallel with R2 (Figure 2). When theswitch is closed, the voltage on RESET IN goes to zero,initiating a reset. Similar to the MAX6412/MAX6413/MAX6414 manual reset, reset remains asserted while theswitch is closed and for the reset timeout period after theswitch is _THSRTFigure 2.

This presents noproblems in most applications, since most µPs andother circuitry do not operate with VCCbelow 1V.

In those applications where RESETmust be valid downto 0, adding a pulldown resistor between RESETandground sinks any stray leakage currents, holdingRESETlow (Figure 6). The value of the pulldown resis-tor is not critical; 100kΩis large enough not to loadRESETand small enough to pull RESETto ground. Forapplications using the MAX6413, MAX6416, andMAX6419, a 100kΩpullup resistor between RESET andVCCwill hold RESET high when VCCfalls below 1V(Figure 7).

The open-drain outputs of the MAX6414/MAX6417/MAX6420 can be used to interface to µPs with otherlogic levels. As shown in Figure 5, the open-drain out-put can be connected to voltages from 0 to 5.5V.

The Maximum Transient Duration Threshold Overdrive graph in the TypicalOperating Characteristicsshows this area below the curve of the graph is the region inwhich these devices typically do not generate a resetpulse. This graph was generated using a negative-going pulse applied to VCC, starting above the actualreset threshold (VTH) and ending below it by the magni-tude indicated (reset-threshold overdrive). As the mag-nitude of the transient decreases (farther below thereset threshold), the maximum allowable pulse widthdecreases. Typically, a VCCtransient that goes 100mVbelow the reset threshold and lasts 50µs or less will notcause a reset pulse to be 6412MAX6415MAX6418VCCRESETGND100kΩNegative-Going VCCTransientsFigure 6.
