30 nA supply — the battery-life anchor
The Texas Instruments TPL5100DGST is a programmable timer IC that draws 30 nA from a 1.8-5 V supply. In a battery-powered sensor waking once per minute, that quiescent current adds under 0.26 mAh per year to the budget — negligible against the self-discharge of a CR2032.
Rated -40 to 105°C, the TPL5100DGST operates across the industrial temperature band — outdoor IoT gateways, engine-bay sensors, and factory-floor controllers all stay within the envelope. The 10-VSSOP package (3.00 mm body width, 0.50 mm pitch) is a standard surface-mount footprint shared with many TI timer and op-amp parts, so the PCB land pattern is already in most library databases.
