TPL5000DGSR

Overview

The TPL5000DGSR is a programmable timer and watchdog timer manufactured by Texas Instruments. It operates within a supply voltage range of 1.8 V to 5 V and features an open-drain output type. The device is housed in a VSSOP-10 package and supports surface mount installation. It functions as a single internal timer with a low operating supply current of 30 nA. The component is rated for operation between -40°C and +105°C, belonging to the TPL5000 series designed for nano-power applications.

Feature Summary

• Ultra-low power consumption with 30 nA operating supply current
• Programmable timer functionality integrated with watchdog timer capabilities
• Wide operating voltage range from 1.8 V to 5 V
• Compact VSSOP-10 surface-mount package

Applications

• Battery-powered embedded systems requiring extended standby life
• Microcontroller reset supervision and watchdog monitoring
• Low-power sensor nodes and IoT devices
• Portable consumer electronics with strict power constraints

Procurement Notes

Verify the specific suffix 'DGSR' corresponds to the tape-and-reel packaging configuration when ordering. Confirm that the VSSOP-10 footprint matches the target PCB design. Ensure the 30 nA quiescent current specification aligns with the system's power budget requirements during sleep modes.

Selection Notes

Select this component when a dedicated hardware watchdog and programmable timeout are required without external microcontroller intervention. Consider the 1.8 V minimum supply voltage for compatibility with modern low-voltage logic families. Evaluate the thermal performance within the -40°C to +105°C range against the intended environmental conditions.

Part Context

This part belongs to the TPL5000 family of nano-power programmable timers. The 'DGSR' designation indicates the specific package style (VSSOP-10) and reel quantity packaging. It serves as a support product for timing and reset management in low-power designs.

Replacement Considerations

Consult official Texas Instruments documentation for direct pin-to-pin replacements or functional equivalents within the same family. Verify electrical parameters such as supply voltage and current consumption before substituting.
