NCP803
Very Low Supply Current
3鈭扨in Microprocessor
Reset Monitor
The 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.
The reset output is driven active within 10
碌sec
of V
CC
falling
through the reset voltage threshold. Reset is maintained active for a
minimum of 140 msec after V
CC
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 V
CC
= 1.0 V and is available
in a SOT-23 package.
The NCP803 is optimized to reject fast transient glitches on the V
CC
line. Low supply current of 1.0
碌A(chǔ)
(V
CC
= 3.2 V) make this device
suitable for battery powered applications.
