TPL5110DDCR

Overview

The TPL5110DDCR is a nano-powered system timer manufactured by Texas Instruments, designed for ultra-low-power applications. It features an integrated MOSFET driver to support power gating in duty-cycled or battery-operated systems. The device operates within a supply voltage range of 1.8V to 5V and consumes only 35nA of current, significantly reducing standby power consumption. Housed in a compact SOT-23-THIN (TSOT-23-6) package, it supports surface-mount installation and functions across a temperature range of -40°C to +105°C.

Feature Summary

• Ultra-low quiescent current consumption of 35 nA
• Integrated high-side MOSFET driver for direct load control
• Programmable timing intervals via external resistor
• Wide operating supply voltage range from 1.8V to 5V

Applications

• Power gating for battery-supplied sensor nodes
• Energy harvesting system management
• Wireless sensor network duty cycling
• Low-power IoT device sleep/wake control

Procurement Notes

Verify the specific suffix 'DDCR' corresponds to the tape-and-reel packaging format when sourcing. Confirm RoHS compliance status and moisture sensitivity level (MSL 1) requirements against assembly specifications. Ensure the ordering quantity aligns with standard reel sizes if bulk procurement is intended.

Selection Notes

Select this component when nanowatt-level standby current is critical for extending battery life in intermittent operation modes. The integrated MOSFET driver simplifies design by eliminating external switching components. Verify that the required timing resolution and maximum interval meet the application needs defined by the external timing resistor.

Part Context

This part belongs to the TPL5110 family of ultra-low-power timers. It serves as a specialized solution for managing power states in energy-constrained environments. The DD variant indicates the thin SOT-23 package, while CR denotes the reel packaging configuration used for automated surface-mount assembly processes.

Replacement Considerations

The TPL5110DDCT is available in cut-tape packaging as an alternative form factor. For automotive applications requiring qualified parts, consider the TPL5110-Q1 series. Direct pin-compatible substitutes within the same family include the TPL5111, which offers similar functionality.
