ON MAX809 Very low supply current 3-pin microprocessor reset monitor Datasheet

MAX809 Series,
MAX810 Series
Very Low Supply Current
3-Pin Microprocessor
Reset Monitors
The MAX809 and MAX810 are cost−effective system supervisor
circuits designed to monitor VCC in digital systems and provide a reset
signal to the host processor when necessary. No external components
are required.
The reset output is driven active within 10 msec of VCC falling
through the reset voltage threshold. Reset is maintained active for a
timeout period which is trimmed by the factory after VCC rises above
the reset threshold. The MAX810 has an active−high RESET output
while the MAX809 has an active−low RESET output. Both devices
are available in SOT−23 and SC−70 packages.
The MAX809/810 are optimized to reject fast transient glitches on
the VCC line. Low supply current of 0.5 mA (VCC = 3.2 V) makes these
devices suitable for battery powered applications.

MAX809 Series, MAX810 Series
Detail Operation Description
The MAX809/810 series microprocessor reset
supervisory circuits are designed to monitor the power
supplies in digital systems and provide a reset signal to the
processor without any external components. Figure 2 shows
the timing diagram and a typical application below. Initially
consider that input voltage VCC is at a nominal level greater
than the voltage detector upper threshold (VTH). And the
If there is an input power interruption and VCC becomes
significantly deficient, it will fall below the lower detector
threshold (VTH−). This event causes the RESET output to be
in the low state for the MAX809, or in the high state for the
NCP810 devices. After completion of the power
interruption, VCC will rise to its nominal level and become
greater than the VTH. This sequence activates the internal
oscillator circuitry and digital counter to count. After the
count of the timeout period, the reset output will revert back
to the original state.
RESET (RESET) output voltage (Pin 2) will be in the high
state for MAX809, or in the low state for MAX 810 devices.

MAX809 Series, MAX810 Series
APPLICATIONS INFORMATION
VCC Transient Rejection
maintained valid to VCC = 0 V, a pull−down resistor must be
connected from RESET to ground to discharge stray
capacitances and hold the output low (Figure 17). This
resistor value, though not critical, should be chosen such that
it does not appreciably load RESET under normal operation
(100 kW will be suitable for most applications).
The MAX809 provides accurate VCC monitoring and
reset timing during power−up, power−down, and
brownout/sag conditions, and rejects negative−going
transients (glitches) on the power supply line. Figure 16
shows the maximum transient duration vs. maximum
negative excursion (overdrive) for glitch rejection. Any
combination of duration and overdrive which lies under the
curve will not generate a reset signal. Combinations above
the curve are detected as a brownout or power−down.
Typically, transient that goes 100 mV below the reset
threshold and lasts 5.0 ms or less will not cause a reset pulse.
Transient immunity can be improved by adding a capacitor
in close proximity to the VCC pin of the MAX809.

MAXIMUM TRANSIENT DURATION (msec)
Duration
Some Microprocessor’s have bidirectional reset pins.
Depending on the current drive capability of the processor
pin, an indeterminate logic level may result if there is a logic
conflict. This can be avoided by adding a 4.7 kW resistor in
series with the output of the MAX809 (Figure 18). If there
are other components in the system which require a reset
signal, they should be buffered so as not to load the reset line.
If the other components are required to follow the reset I/O
of the Microprocessor, the buffer should be connected as
shown with the solid line.

The MAX809 RESET output is valid to VCC = 1.0 V.
Below this voltage the output becomes an “open circuit” and
does not sink current. This means CMOS logic inputs to the
Microprocessor will be floating at an undetermined voltage.
Most digital systems are completely shutdown well above
this voltage. However, in situations where RESET must be
