TPS3600D20PWR

Supervisors Overview

The TPS3600D20PWR is a voltage supervisory circuit manufactured by Texas Instruments, designed for low-power processor battery backup applications. It operates within a supply voltage range of 1.65 V to 5.5 V and features a threshold voltage of 1.91 V. The device monitors one input with an active low, push-pull output type and includes manual reset functionality alongside a watchdog timer. Key electrical parameters include a reset delay time of 100 ms, a maximum power dissipation of 700 mW, and a typical operating supply current of 20 uA. It supports chip enable signals and detects power failures.

Supervisors Feature Summary

• Integrates battery backup switching capabilities for low-power processors
• Includes built-in watchdog timer for system reliability monitoring
• Provides manual reset control via dedicated input pin
• Features power failure detection with active low push-pull output

Supervisors Applications

• Low-power processor battery backup systems
• Voltage supervision in portable electronic devices
• System reset management in embedded controllers

Supervisors Procurement Notes

Verify the specific suffix D20PWR corresponds to the required threshold voltage and package configuration. Confirm RoHS compliance status through official manufacturer documentation before procurement. Ensure the TSSOP-14 footprint matches the design layout requirements. Check for any recent product lifecycle changes or obsolescence notices from Texas Instruments.

Supervisors Selection Notes

Select this component when a single-input voltage supervisor with integrated battery backup and watchdog functions is required. The 1.91 V threshold suits applications monitoring lower voltage rails. Consider the 20 uA quiescent current for battery-sensitive designs. Verify that the TSSOP-14 package is suitable for the assembly process and thermal constraints of the target application.

Supervisors Part Context

This part belongs to the TPS3600 series of voltage supervisory circuits from Texas Instruments. The series focuses on providing comprehensive power management solutions including reset generation, battery switching, and watchdog timers. The D20 variant specifically denotes the threshold voltage characteristics, while PWR indicates the TSSOP-14 surface-mount package type.

Supervisors Replacement Considerations

Consult the TPS3600 datasheet for direct pin-compatible alternatives within the same family. Verify that substitute parts maintain the 1.91 V threshold and TSSOP-14 package dimensions. Cross-reference functional equivalents only if the original component is unavailable.
