CAT811MTBI-T3

Supervisors Overview

The CAT811MTBI-T3 is a voltage supervisory circuit manufactured by onsemi, designed for monitoring single power supply rails. It features an active low push-pull output and includes manual reset functionality. The device operates within a supply voltage range of up to 5 V and supports threshold voltages including 2.5 V, 3 V, 3.3 V, and 5 V. Key electrical parameters include a reset delay time of 240 ms, a quiescent current of 8 uA, and an overvoltage threshold of 2.35 V. It is housed in a SOT-143-4 surface-mount package and functions across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides manual reset capability for system control
• Delivers active low push-pull output signal
• Monitors a single voltage input channel

Supervisors Applications

• Portable equipment power management
