S-80849CNMC-B9AT2G

Supervisors Overview

The S-80849CNMC-B9AT2G is a high-precision voltage detector from the ABLIC S-808xxC series, designed for monitoring power supply voltages in portable electronic devices. It features a fixed detection threshold of 4.9 V with an accuracy of ±2.0%. The device operates within a supply voltage range of 0.95 V to 10.0 V and consumes a typical quiescent current of 1.3 µA. It provides an N-channel open-drain output that activates low when the monitored voltage falls below the threshold. The component is housed in a compact SC-82AB (SOT-343) surface-mount package and supports an adjustable reset delay time.

Supervisors Feature Summary

• High-precision voltage detection with ±2.0% accuracy
