MAX803 Series,
NCP803 Series
Very Low Supply Current
3-Pin Microprocessor
Reset Monitor
The MAX803/NCP803 is a cost ? effective system supervisor circuit
designed to monitor V CC in digital systems and provide a reset signal to
the host processor when necessary. No external components are
required.

MARKING
DIAGRAM
The reset output is driven active within 10 m sec of V CC falling
through the reset voltage threshold. Reset is maintained active for a
timeout period which is trimmed by the factory after V CC rises above
the reset threshold. The MAX803/NCP803 has an open drain
active ? low RESET output. Both devices are available in SOT ? 23 and

The MAX803/NCP803 is optimized to reject fast transient glitches
on the V CC line. Low supply current of 0.5 m A (V CC = 3.2 V) make
these devices suitable for battery powered applications.
