30 nA supply — the spec that defines the fit
The headline rating is 30 nA supply current — not a standby mode, not a shutdown current, but the operating draw of the timer itself. This places the TPL5100DGSR in the nano-power class: a battery-powered sensor node that wakes once per minute to take a reading and transmit can run for years on a coin cell, with the timer's own draw well below the cell's self-discharge rate.
Industrial temperature grade and small-footprint package
An outdoor data logger or an engine-bay timer that sees 85°C on a hot day still has 20°C of margin before the upper spec limit. The 0.50 mm pitch demands a standard 4-layer PCB for fan-out; two-layer boards break out only the outer pins.
ROHS3 compliant per Texas Instruments' declaration — no exemption-ridden transition materials.
