APPLICATIONS INFORMATION  
Benefits of Precision Reset Thresholds  
A microprocessor supply supervisor must provide a reset output within a predictable range of the supply voltage.  
A common threshold range is between 5% and 10% below the nominal supply voltage. The 4.63V and 3.08V  
options of the LM809/810 use highly accurate circuitry to ensure that the reset threshold occurs only within this  
range (for 5V and 3.3V supplies). The other voltage options have the same tight tolerance to ensure a reset  
signal for other narrow monitor ranges. See Table 1 for examples of how the standard reset thresholds apply to  
3V, 3.3V, and 5V nominal supply voltages.

Ensuring a Valid Reset Output Down to VCC = 0V  
When VCC falls below 1V, the LM809 RESET output no longer sinks current. A high-impedance CMOS logic  
input connected to RESET can therefore drift to undetermined voltages. To prevent this situation, a 100kΩ  
resistor should be connected from the RESET output to ground, as shown in Figure 9.  
A 100kΩ pull-up resistor to VCC is also recommended for the LM810, if RESET is required to remain valid for VCC  
< 1V.  
Figure 9. RESET Valid to VCC = Ground Circuit  
Negative-Going VCC Transients  
The LM809/810 are relatively immune to short negative-going transients or glitches on VCC. Figure 10 shows the  
maximum pulse width a negative-going VCC transient can have without causing a reset pulse. In general, as the  
magnitude of the transient increases, going further below the threshold, the maximum allowable pulse width  
decreases. Typically, for the 4.63V and 4.38V version of the LM809/810, a VCC transient that goes 100mV below  
the reset threshold and lasts 20µs or less will not cause a reset pulse. A 0.1 µF bypass capacitor mounted as  
close as possible to the VCC pin will provide additional transient rejection.
