Supervisors datasheet and documents for FM1233ABAS3X

FM1233ABAS3X

Supervisors Overview

The FM1233ABAS3X is a fixed-supervisory circuit manufactured by Fairchild Semiconductor. It operates within a supply voltage range of 4.5 V to 5.5 V, with a nominal rating of 5 V. The device provides one channel of power supply monitoring and features a fixed threshold without adjustability. It is housed in a SOT-23 package (PDSO3) with three pins. The component supports an operating temperature range from -40 °C to 105 °C.

Supervisors Feature Summary

Provides fixed power supply supervision for a single channel
Operates on standard 5 V logic supplies
Compact surface-mount SOT-23 packaging

Supervisors Applications

5 V digital system power monitoring
Embedded controller reset generation
Portable electronic device power management

Supervisors Procurement Notes

Verify the specific suffix 'BAS3X' against official Fairchild documentation to confirm pinout and electrical characteristics. Ensure the source document explicitly identifies this part as a supervisory circuit. Confirm RoHS compliance status if required by your design specifications. Cross-reference the manufacturer name with current ownership records.

Supervisors Selection Notes

Select this component when a fixed threshold supervisor is required for 5 V rails. The SOT-23 form factor suits space-constrained designs. Verify that the fixed trip point meets the specific voltage tolerance requirements of the monitored circuit. Consider the industrial temperature range for harsh environments.

Supervisors Part Context

This part belongs to the FM1233 series of power supply support circuits. Similar variants include FM1233ACS3X and FM1233DDS3. These devices share the same core supervisory function but may differ in package type or specific electrical tolerances. The series is designed for reliable monitoring in consumer and industrial electronics.
