TPL5000DGST

Overview

The TPL5000DGST 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 consumes a typical operating supply current of 30 nA. The device features an open-drain output and contains one internal timer. It is housed in a 10-VSSOP package with dimensions of 3.00 mm width. The component supports surface mount installation and functions reliably across an extended temperature range from -40°C to +105°C.

Feature Summary

• Ultra-low power consumption with 30 nA operating supply current
• Programmable timer functionality with integrated watchdog timer
• Wide supply voltage operation from 1.8 V to 5 V
• Open-drain output configuration for flexible interfacing

Applications

• Battery-powered IoT sensor nodes requiring minimal standby current
• Microcontroller system reset and watchdog supervision
• Low-power wearable electronics and medical devices
• Industrial control systems needing reliable timer management

Procurement Notes

Verify the specific suffix 'DGST' indicates the tape-and-reel packaging variant with a standard factory quantity of 250 units. Confirm RoHS compliance status through official datasheets, as environmental declarations may vary by production batch. Ensure compatibility with 10-VSSOP footprint requirements during PCB layout design.

Selection Notes

Select this component when ultra-low quiescent current is critical for battery life extension. Compare against the TPL5000DGSR if reel quantities differ significantly for your assembly line needs. Verify that the open-drain output capability meets the logic level requirements of the connected microcontroller or system controller.

Part Context

This part belongs to the TPL5000 series of nano-power programmable timers. It serves as a support product for maintaining system integrity in low-power applications. The DGST designation specifically identifies the 250-unit tape-and-reel packaging option provided by Texas Instruments for automated surface-mount assembly processes.

Replacement Considerations

The TPL5000DGSR is a direct functional equivalent differing primarily in packaging quantity (3500 units per reel). Evaluate inventory requirements and reflow profile compatibility when substituting between DGST and DGSR variants.
