Application Notes
The propagation delay time for the LM8364 is measured
using a 470k
pull-up resistor connected to from the RESET
output pin to 5V in addition to a 10pF capacitive load con-
nected from the same pin to GND. Figure 1 shows the timing
diagram for the measurement for the propagation delay.
V
DET+ is equal to the sum of the detector threshold, VDET,
and the built in hysteresis, V
HYS.
The LM8364 ultra-low current voltage detector was designed
to monitor voltages and to provide an indication when the
monitored voltage, V
IN, dropped below a precisely trimmed
threshold voltage. This characteristic is displayed in the typi-
cal operating timing diagram below. V
IN is the voltage that is
being monitored and a pull up resistor is connected from the
RESET output pin to V
IN.VIN is at some value above VDET+
and then begins to decrease. Since this is an Active Low
device the RESET output is pulled High through the pull-up
resistor and tracks V
IN until VIN crosses the trimmed thresh-
old V
DET. At this point the LM8364 recognizes that VIN is
now in a fault condition and the output immediately changes
to the Logic Low State. The RESET output will remain in this
low state until V
IN increases above the threshold VDET +
V
HYS. This point is also known as VDET+ as indicated earlier.
This built-in hysteresis has been added to the design to help
prevent erratic reset operation when the input voltage
crosses the threshold.
The LM8364 has a wide variety of applications that can take
advantage of its precision and low current consumption to
monitor Input voltages even though it was designed as a
reset controller in portable microprocessor based systems. It
is a very cost effective and space saving device that will
protect your more expensive investments of microproces-
sors and other devices that need a guaranteed supply volt-
age for proper operation.
