NCP803SN400T1G IC SUPERVISOR 1 CHANNEL SOT23-3 onsemi

 

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 MAX803/NCP803 is optimized to reject fast transient glitches on the VCC line. Low supply current of 0.5 μA (VCC = 3.2 V) make these devices suitable for battery powered applications.
