Overview

The onsemi CAT809STBI-GT3 is a crucial component for ensuring system stability by providing a precise voltage monitoring and reset function. Its primary role is to detect undervoltage conditions and assert a reset signal, preventing erratic behavior in sensitive digital circuits. A key design consideration often overlooked is the trade-off between reset assertion speed and power consumption; while faster resets are desirable, they can increase quiescent current. This particular device offers a robust solution with a 140ms minimum reset timeout, balancing prompt fault detection with efficient operation for its intended applications.

Key Features

Voltage Monitoring Threshold: 2.93V
Output Type: Push-Pull, Totem Pole
Reset Logic: Active Low
Reset Timeout: 140ms Minimum
Operating Temperature: -40°C to 85°C
Package: SOT-23-3 (TO-236-3, SC-59)

Applications

The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.

Power sequencing for microcontrollers and DSPs
System reset generation in battery-powered portable devices
Voltage supervision in industrial control systems
Ensuring proper boot-up sequence in embedded computing platforms
