TPL5100DGST

Overview

The TPL5100DGST is a nano-power programmable timer integrated circuit manufactured by Texas Instruments. It operates within a supply voltage range of 1.8 V to 5 V and consumes a typical operating current of 30 nA at 2.5 V. The device provides selectable timing intervals ranging from 16 seconds to 1024 seconds. Designed for low-power applications, it allows microcontrollers to remain completely off during idle periods, reducing total power consumption by 60% to 80%. The component is housed in a 10-pin VSSOP package and supports surface-mount installation.

Feature Summary

• Ultra-low power consumption of 30 nA (typical) at 2.5 V
• Programmable timer intervals selectable between 16 and 1024 seconds
• Integrated MOS driver for power gating applications
• Supply voltage range of 1.8 V to 5.0 V

Applications

• Battery-powered systems
• Energy harvesting systems
• Remote data-logger nodes
• Sensor node monitoring
• Power-gating applications

Procurement Notes

Verify the specific suffix 'DGST' corresponds to the cut-tape or MouseReel packaging format when ordering, as distinct from the reel-based 'DGSR' variant. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the 10-pin VSSOP footprint matches the target PCB layout constraints. Cross-reference the latest datasheet revision to confirm pinout consistency with existing designs.

Selection Notes

Select the TPL5100DGST when timing durations between 16 and 1024 seconds are required for periodic wake-up cycles. This component is suitable for replacing internal microcontroller timers to achieve significant power savings in sleep modes. Verify that the load connected to the MOS driver output aligns with the device's drive capabilities. Consider the -40°C to +105°C operating temperature range for environmental suitability.

Part Context

The TPL5100DGST belongs to the TPL5100 series of nano-power programmable timers. It serves as a specialized support product designed to manage power states in energy-constrained environments. The device complements other Texas Instruments timer solutions like the TPL5000, which includes watchdog functionality, whereas the TPL5100 focuses on long-term interval timing and power gating via an integrated driver.
