TPS3705-50DRG4

Supervisors Overview

The TPS3705-50DRG4 is a voltage supervisory circuit manufactured by Texas Instruments, designed for processor monitoring applications. It operates within a supply voltage range of 2 V to 6 V and features an adjustable threshold voltage with a typical value of 4.55 V. The device monitors two inputs and provides active low, push-pull outputs. Key functional attributes include manual reset capability, an integrated watchdog timer, and a reset delay time of 200 ms. It lacks battery backup switching functionality. The component is housed in an SOIC-8 surface-mount package and supports operation across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Supports manual reset input for user-initiated control
• Provides dual-channel voltage supervision with active low push-pull outputs

Supervisors Applications

• Processor power-fail detection
• Voltage supervisory circuits
• Embedded system reset management

Supervisors Procurement Notes

Verify the specific suffix 'DG4' indicates lead-free compliance and RoHS status as per manufacturer documentation. Confirm the 'R' designation in the full part number corresponds to tape-and-reel packaging when sourcing from distributors. Ensure the selected variant matches the required operating temperature range and package type for the target application design.

Supervisors Selection Notes

Select this component when dual-input voltage monitoring with watchdog functionality is required. The adjustable threshold allows flexibility for various supply rails. Consider the SOIC-8 package constraints and the 200 ms reset delay timing against system requirements. Verify compatibility with the target processor's reset signal polarity and current drive capabilities.
