TPS3123J12DBVT

Supervisors Overview

The TPS3123J12DBVT is a voltage supervisory circuit manufactured by Texas Instruments, designed for ultra-low voltage processor applications. It operates within a supply voltage range up to 3.3 V and features a threshold voltage of 1.08 V with an overvoltage threshold of 1.12 V. The device provides active high and active low push-pull outputs, includes a manual reset function, and incorporates a watchdog timer. It has a reset delay time of 180 ms and maintains an accuracy of 3.7%. The component draws a working supply current of 14 uA and is housed in a SOT-23-5 package, suitable for surface mount installation across temperatures from -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Provides dual active high and active low push-pull output configurations
• Supports manual reset functionality via external input

Supervisors Applications

• Ultra-low voltage processor supervision
• Portable electronic devices requiring low power monitoring
• Battery-powered systems with voltage threshold protection

Supervisors Procurement Notes

Verify the specific suffix 'DBVT' confirms the tape and reel packaging variant distinct from 'DBVR'. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the datasheet revision to validate electrical characteristics against current production standards.

Supervisors Selection Notes

Select this component when a single-channel supervisor with both undervoltage and overvoltage detection is required. The integrated watchdog timer distinguishes it from simpler reset controllers. The SOT-23-5 package offers a compact footprint for space-constrained designs. Consider the 14 uA quiescent current for battery life optimization in always-on circuits.
