MARKING  
DIAGRAM  
The MAX803/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.  
3
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 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 VCC line. Low supply current of 0.5 mA (VCC = 3.2 V) make  
these devices suitable for battery powered applications.
