TPL5100DGSR

Overview

The TPL5100DGSR is a programmable timer integrated circuit manufactured by Texas Instruments, designed for ultra-low power applications. It operates within a supply voltage range of 1.8 V to 5 V and consumes only 30 nA of quiescent current. The device features an internal oscillator and supports external timing components for precise interval control. Housed in a compact 10-VSSOP package, it functions reliably across an industrial temperature range from -40°C to +105°C. This component integrates power gating capabilities to minimize standby consumption, making it suitable for battery-operated systems requiring extended operational life.

Feature Summary

• Ultra-low quiescent current of 30 nA
• Programmable timing intervals via external resistor and capacitor
• Integrated power gating output for system sleep control
• Wide operating voltage range: 1.8 V to 5 V

Applications

• Battery-powered sensor nodes with periodic wake-up requirements
• Low-power IoT devices requiring long standby periods
• Watchdog timer implementations in microcontroller systems
• Power management circuits for energy harvesting applications

Procurement Notes

Verify the specific suffix 'DGSR' corresponds to the 10-VSSOP package and reel packaging configuration. Confirm RoHS compliance status through official Texas Instruments documentation prior to integration. Ensure compatibility with the target PCB footprint and soldering profile for surface-mount assembly.

Selection Notes

Select this component when nanowatt-level standby current is critical. Verify that the required timing resolution matches the external RC network capabilities. Consider the 10-VSSOP package constraints for thermal dissipation and board space. Validate input voltage stability against the 1.8 V minimum threshold during operation.

Part Context

This part belongs to the TPL5100 series of nano-power programmable timers. It is distinct from general-purpose oscillators due to its integrated power gating feature. The DGSR suffix indicates the specific tape-and-reel packaging variant intended for automated surface-mount production lines.

Replacement Considerations

Direct pin-to-pin replacements within the same family include other TPL5100 variants with different suffixes indicating package or temperature grade changes. Cross-family substitution requires verification of timing accuracy, current consumption, and output drive capability against original specifications.
