Product Summary

The NCP803SN308T1G 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 of the NCP803SN308T1G is driven active within 10 usec 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 NCP803SN308T1G has an open drain active-low RESET output. The device is available in SOT-23 and SC-70packages. The NCP803SN308T1G is optimized to reject fast transient glitches on the VCC line. Low supply current of 0.5 uA (VCC = 3.2 V) make the device suitable for battery powered applications.
