MARKING

The MAX803/NCP803 is a cost−effective system supervisor circuit

designed to monitor V_CCin digital systems and provide a reset signal to

the host processor when necessary. No external components are

required.

DIAGRAM

The reset output is driven active within 10 msec of V_CCfalling

through the reset voltage threshold. Reset is maintained active for a

timeout period which is trimmed by the factory after V_CCrises above

the reset threshold. The MAX803/NCP803 has an open drain

active−low RESET output. Both devices are available in SOT−23 and

SC−70 packages.

The MAX803/NCP803 is optimized to reject fast transient glitches

on the V_CCline. Low supply current of 0.5 mA (V_CC= 3.2 V) make

these devices suitable for battery powered applications.

APPLICATIONS INFORMATION

V_CCTransient Rejection

the NCP803/MAX803 has Open−Drain and active−low

output, it typically uses a pullup resistor. With this device,

RESET will most likely not maintain an active condition,

but will drift to a non−active level due to the pullup resistor

and the reduced sinking capability of the open−drain device.

Therefore, this device is not recommended for applications

where the RESET pin is required to be valid down to

The MAX803/NCP803 series provides accurate V_CC

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 11 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 V_CCpin of the

MAX803.

In numerous applications the pullup resistor place on the

RESET output is connected to the supply voltage monitored

by the IC. Nevertheless, a different supply voltage can also

power this output and so level−shift from the monitored

supply to reset the microprocessor. However, if the

NCP803/MAX803’s supply goes blew 1 V, the RESET

output ability to sink current will decrease and the result is

a high state on the pin even though the supply’s IC is under

the threshold level. This occurs at a V level that depends

value and the voltage which is connected.

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 V_CC= 0 V, since
