Supervisors datasheet and documents for CAT809TTBI-T3

CAT809TTBI-T3

Supervisors Overview

The CAT809TTBI-T3 is a microprocessor power supply supervisor manufactured by onsemi, designed to monitor digital system voltages. It operates within a supply voltage range of 1.2 V to 5.5 V and features a fixed reset threshold of 3.08 V. The device utilizes an active-low push-pull output and provides a minimum reset delay time of 140 ms. Packaged in a compact SOT-23-3 surface-mount format, it supports an operating temperature range from -40 °C to +85 °C.

Supervisors Feature Summary

Generates a reset signal when the monitored power supply voltage falls below a preset threshold level
Features an active-low push-pull output configuration for direct interface with digital logic
Provides a guaranteed minimum reset delay time to ensure stable power-up sequencing

Supervisors Applications

Monitoring power supplies in digital systems requiring voltage supervision
Serving as a direct replacement for legacy MAX809 supervisory circuits
Industrial applications operating within the specified temperature range

Supervisors Procurement Notes

Verify component authenticity through authorized distribution channels due to potential availability constraints. Confirm specific manufacturing lot details against current datasheet revisions. Ensure compatibility with existing PCB footprints and thermal management requirements before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when a fixed 3.08 V threshold is required for single-channel monitoring. The push-pull output eliminates the need for external pull-up resistors compared to open-drain alternatives. Consider the SOT-23-3 package size for space-constrained designs requiring industrial temperature operation.

Supervisors Part Context

This part belongs to the CAT809 series of 3-pin microprocessor power supply supervisors. It is functionally compatible with the MAX809 family, offering direct pin-to-pin replacement capabilities. The series is designed for reliable voltage supervision in embedded digital environments.
