LTC2912IDDB-3#TRMPBF

Supervisors Overview

The LTC2912IDDB-3#TRMPBF is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single voltage rails. It operates within a supply voltage range of 1.62V to 5.5V and draws a typical quiescent current of 40µA. The device features an open-drain reset output with a selectable timeout delay ranging from 1ms to 10s. It supports under-voltage and over-voltage monitoring thresholds, with the '3' suffix indicating specific threshold settings. Packaged in an 8-lead DFN (3x2mm) case, it functions reliably across an industrial temperature range of -40°C to +85°C.

Supervisors FAQ

What is the function of the open-drain reset output?

The open-drain reset output signals when the monitored voltage is outside the acceptable range, allowing connection to a pull-up resistor for logic interface compatibility.

How is the reset timeout delay determined?

The timeout delay is selectable via external components or internal configuration, typically ranging from 1ms to 10s depending on the specific variant and pin connections.
