DATA SHEET www.onsemi.com Very Low Supply Current 3-Pin Microprocessor Reset Monitor MAX803 Series, NCP803 Series 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 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.
