MAX803 Series, NCP803 Series Very Low Supply Current3-Pin Microprocessor Reset Monitor

2021-12-14
●Description
■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.
■The reset output is driven active within 10 sec 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 andSC−70 packages.
■The MAX803/NCP803 is optimized to reject fast transient glitches on the V-CC line. Low supply current of 0.5 uA (V-CC= 3.2 V) make these devices suitable for battery powered applications.
