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.

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

RESET (RESET) output voltage (Pin 2) will be in the high

state for MAX809, or in the low state for MAX 810 devices.

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.

APPLICATIONS INFORMATION

VCC Transient Rejection

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.

RESET Signal Integrity During Power−Down

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

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).

Processors With Bidirectional I/O Pins

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.
