LTC2919HMS-2.5#PBF

Supervisors Overview

The LTC2919HMS-2.5#PBF is a precision supervisory circuit manufactured by Analog Devices Inc., designed for monitoring multiple voltage rails in embedded systems. It features three independent input channels capable of detecting under-voltage, over-voltage, and negative voltage conditions simultaneously. The device utilizes an open-drain output configuration to signal fault states or assert a reset signal when monitored voltages exceed predefined thresholds. Packaged in a compact MSOP-10 surface-mount format, it supports a maximum supply voltage of 6 V and operates within a temperature range of -40°C to +85°C. The component offers high accuracy with a threshold tolerance of 1.5% and consumes a low quiescent current of 50 uA, making it suitable for power-sensitive applications requiring reliable system supervision.
