Product details

What this programmable timer does and why the 35 nA matters

The TPL5110DDCR is a programmable timer from Texas Instruments that generates a single output pulse after a user-set delay period, drawing only 35 nA from the supply while waiting. That 35 nA quiescent current is the headline spec — it is low enough that a battery-powered sensor node can leave the timer running continuously for years without draining the cell, making it a fit for periodic wake-up circuits in energy-harvesting or long-life IoT endpoints.

Package and board-fit for the TSOT-23-6

The TPL5110DDCR comes in a TSOT-23-6 package (SOT-23-6 Thin), a surface-mount footprint with 0.95 mm pitch that routes easily on a two-layer board. The supplier device package is SOT-23-THIN, which is the same physical outline as the standard SOT-23-6 but with a thinner body — the PCB land pattern is identical, so no footprint change is needed if you are migrating from a standard SOT-23-6 timer.

Lifecycle and compliance — active, RoHS3, no obsolescence watch

The part is ROHS3 Compliant, so it meets the current EU restriction on hazardous substances without an exemption. For a BOM that needs a long-life timer with a known supply chain, this is a straightforward line item to commit.

Frequently asked questions

What is the supply current of the TPL5110DDCR and why does it matter?

The supply current is 35 nA typical. That is the current the timer draws while waiting for the programmed delay to elapse — it is roughly 1000× lower than a typical microcontroller in sleep mode, so a battery-powered system can leave the timer running continuously and still achieve multi-year battery life on a coin cell.

What package does the TPL5110DDCR come in?

It is supplied in a TSOT-23-6 (SOT-23-6 Thin) surface-mount package. The supplier device package is SOT-23-THIN. The footprint is the same as a standard SOT-23-6, but the body is thinner — no PCB land-pattern change is needed if you are replacing a standard SOT-23-6 timer.
