NCP803
Very Low Supply Current
3−Pin Microprocessor
Reset Monitor
The NCP803 is a cost−effective system supervisor circuit 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
minimum of 140 msec after VCC rises above the reset threshold. The
NCP803 has an open drain active−low RESET output. The output of
the NCP803 is guaranteed valid down to VCC = 1.0 V and is available
in a SOT−23 package.

The NCP803 is optimized to reject fast transient glitches on the VCC
line. Low supply current of 1.0 mA (VCC = 3.2 V) make this device
suitable for battery powered applications.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.
